▼ For
spatial data visualization, we approach two problems and provide solutions: heat map resolution selection, and heat map confidence interval presentation. Analysts often present
spatial data in gridded heat maps, at some chosen resolution. However, many data types vary in density across the domain. We develop variable-resolution heat maps to visually accommodate this changing density, and an R package, varyres, to implement it. Further, heat map confidence intervals typically consist of two heat maps, one for each confidence interval bound. We develop an interactive heat map confidence interval that changes dynamically as a user moves through the interval surfaces; and an R package, mapapp, to implement it.
For
spatial data analysis, Bayesian hierarchical models work well for accommodat- ing complex
spatial correlation structures. However, with big
spatial data we face a com- putational bottleneck on the order of n3. We delineate, use, and assess three approaches to addressing the "big N" problem with our
spatial baseball strike zone data. Hamil- tonian Monte Carlo implemented with Stan proved too slow despite computational op- timization. Predictive Process Models, a dimension reduction technique implemented with spBayes, were much faster but Markov chains failed to converge. Integrated Nested Laplace Approximation was the only successful method.

▼ The 2009 H1N1 pandemic caused serious concerns worldwide due to the novel biological feature of the virus strain, and the high morbidity rate for youth. The urban scale is crucial for analyzing the pandemic in metropolitan areas such as the Greater Toronto Area (GTA) of Canada because of its large population. The challenge of exploring the spatial dynamics of H1N1 is exaggerated by data scarcity and the absence of an immediately applicable methodology at such a scale. In this study, a stepwise methodology is developed, and a retrospective spatial statistical analysis is conducted using the methodology to estimate the spatial dynamics of the 2009 H1N1 pandemic in the GTA when the data scarcity exists. The global and local spatial autocorrelation analyses are carried out through the use of multiple spatial analysis tools to confirm the existence and significance of spatial clustering effects. A Generalized Linear Mixed Model (GLMM) implemented in Statistical Analysis System (SAS) is used to estimate the area-specific spatial dynamics. The GLMM is configured to a spatial model that incorporates an Intrinsic Gaussian Conditionally Autoregressive (ICAR) model, and a non-spatial model respectively. Comparing the results of spatial and non-spatial configurations of the GLMM suggests that the spatial GLMM, which incorporates the ICAR model, proves a better predictability. This indicates that the methodology developed in this study can be applied to epidemiology studies to analyze the spatial dynamics in similar scenarios.

Primate frontal eye fields mediate spatial attention in

▼ Visual
spatial attention serves to select locations of
interest in the visual field and enhances the cortical
representation of objects at those locations. Previous studies
suggest that neural activity in primate frontal eye fields (FEF) is
involved in the
spatial selection of salient stimuli in complex
visual environments for eye movements and
spatial attention. Here,
we explore the origin of the
spatial selection signal in FEF and
its relationship to measures of covert
spatial attention. We
compare the timing of
spatial selection for the location of the
target in two simultaneously recorded cortical signals: local field
potentials (LFPs) and spikes. LFPs are thought to represent
synaptic input, while spiking activity is the output, of the area
around the electrode tip. We found that
spatial selectivity
identifying the location of the target in the visual search
appeared in the spikes about 30 ms before it appeared in the LFPs.
This suggests that the
spatial selection signal is computed locally
in FEF from spatially non selective inputs. Additionally, we show
that the magnitude of
spatial selection in FEF is related to
behavioral measures of attention during the time period in which
the stimulus is being processed by the visual system. This
relationship shows that FEF is directly involved in
spatial
attention.

▼ This dissertation critically examined the structure of
human
spatial knowledge by testing three general hypotheses: the
Euclidean, Topological, and Stability Hypotheses. The present
experiments selectively destabilized three geometric properties of
the environment during learning, specifically Euclidean metric
structure, neighborhoods, or the place graph. In the learning
phase, separate groups of participants walked in one of four
virtual hedge mazes: (1) The Control Maze preserved all three
properties. (2) Elastic Maze I preserved the place graph while
destabilizing Euclidean and neighborhood structure, by stretching
paths during learning so that a target could occupy two different
metric locations in different neighborhoods. This maze provided
metric (via path integration) but not visual information about
neighborhood boundary relations. (3) Elastic Maze II added visual
information for neighborhood boundaries, by having stretched paths
visibly intersect paths they crossed during learning. (4) The Swap
Maze preserved neighborhoods while destabilizing Euclidean and
graph structure by swapping pairs of targets within a neighborhood
during learning. In the test phase,
spatial learning was probed by
asking participants to perform one of three navigational tasks: (a)
metric shortcut task, designed to assess Euclidean
spatial
knowledge, (b) neighborhood shortcut task, to assess knowledge of
neighborhoods, (c) route task, to assess graph knowledge. This
design aimed to test several specific predictions: (H1) if
spatial
knowledge is primarily Euclidean, then performance on all tasks
should deteriorate when metric structure is destabilized during
learning; (H2) if
spatial knowledge is primarily topological,
performance should reflect the place graph when metric and
neighborhood structure are destabilized, and (H3) if navigators
acquire whatever geometric properties remain stable during
learning, performance should reflect the stable structure in each
maze. The results are inconsistent with the Euclidean and Stability
hypotheses, but support the Topological hypothesis. Metric
performance is highly unreliable and neighborhood knowledge can
suffer even when neighborhoods are stable. In contrast, the place
graph is successfully learned in all environments, with over 96%
accuracy.
Spatial knowledge appears to be primarily topological,
and is consistent with a labeled graph that incorporates
approximate local distance and angle information.

▼ It seems intuitively obvious that active exploration
of a new environment would lead to better
spatial learning than
passive exposure. However, the literature on this issue is
decidedly mixed, in part because the concept itself is not well
defined. This dissertation identifies and tests the contributions
of five components to
spatial learning: visual information,
vestibular information, motor/proprioceptive information, cognitive
decision-making, and the allocation of attention. Participants
learned the locations of eight objects in an ambulatory virtual
maze environment, and were then tested on their graph or survey
knowledge of the environment. During learning, participants
explored the maze by (1) walking, (2) being pushed in a wheelchair,
or (3) sitting watching a video, and either (1) made decisions
about exploration or (2) were guided through the maze. In
Experiment 1, survey knowledge was tested with a direct shortcut
task in a desert environment, walking in a straight line from
object A to object B. In Experiment 2, graph knowledge was tested
with a shortest route task, walking from A to B in the maze
hallways, with detours. In Experiment 3, attention during learning
was manipulated with an orienting task, by providing instructions
and practice to orient attention to either the survey or the graph
structure of the environment. The results suggest that (a)
idiothetic information in walking contributes to metric survey
knowledge, (b) decision-making during exploration contributes to
graph knowledge, and (c) orienting tasks that direct attention to
relevant environmental properties do not contribute to graph
knowledge beyond the contributions of decision-making. The effects
of decision-making in the graph test were most prominent with full
idiothetic information, which may explain previous mixed results in
desktop VR. In addition, large sex differences and individual
differences were observed, which may reflect another component of
active
spatial learning: mental manipulation of
spatial
information. Thus, there is indeed an active advantage in
spatial
learning, however, different components of active learning
contribute differently to graph and survey knowledge.

▼ Since 1998, the invasive insect amber-marked birch leaf miner (Profenusa thomsoni Konow.) has been an issue for the birch trees in Alaska's Anchorage Bowl. P. thomsoni is native to Europe and an invasive defoliator of birch trees; its impacts are considered aesthetically unpleasing to Anchorage residents. In this study, a
spatial and temporal model was constructed using a cellular automata (CA) method. Employing the statistical program R (R Development Core Team 2008), coupled with a custom library called RandomFields (Schlather 2012) and linear regression techniques, a CA model was created. Using five years of field data gathered between 2006 and 2010 (Lundquist et al. 2012), the CA model mimics the observed change in severity of the infestation based upon the severity in the previous year and if the region was in an area that increased or decreased in severity. A voracity test was used to compare the CA model output for the time period of the observed field data; a sensitivity analysis on various input parameters was also implemented. The CA model simulated results were analyzed for the time period 1998 to 2018 and indicated that P. thomsoni may follow three primary phases: 1) expansion, 2) decline, and 3) equilibrium. The expansion phase demonstrated a six-year
spatial spread cycle, which can be described as random, disjointed regions of high infestation that move about the landscape. The expansion phase may be the result of an abundance of host, lack of natural enemies, and no density-dependent factors. The declining phase is depicted as a decrease in severity at an increase rate. The declining phase is possibly due to the combination of density-dependent factors and natural enemies. The equilibrium phase is a possible product of long-term plant defenses. The development of this
spatial and temporal predictive CA model will allow resource managers to be proactive in order to mitigate and manage the P. thomsoni infestation. In addition, this modeling method can be used to simulate other forest pests and pathogens at the landscape level.

▼ One of the goals of computer vision research is to
design systems that provide human-like visual capabilities such
that a certain environment can be sensed and interpreted to take
appropriate actions. Among the different forms available to
represent such an environment, the 3D point cloud (unstructured
collection of points in a three dimensional space) rises a lot of
challenging problems. Moreover, the number of 3D data collection
drastically increased in recent years, as improvements in the laser
scanners technology, together with algorithms for combining
multiple range and color images, allowed to accurately digitize any
amount of 3D scenes. Because of these developments, some important
digitalization projects: like the digital Michelangelo project or
the digitalization of the Pantheon. - were achieved. The
last project, conducted by the Karman Center1, generated a 3D
digital model (available as a validation data set for our research
study) containing more than 620'000'000 points. If the
universe (or unstructured space) is given by all 3D points
generated by the acquisition device, then calibrated, registered,
and finally stocked in a
spatial database system - then a scene is
a limited region of this universe, having a regular geometric form
and containing (un)known 3D objects. The interpretation of a scene
is defined as learning which model is located where in the scene.
Such an interpretation binds the entities in the scene to the
models that we already known. Following the recent trend consisting
in applying the AI point of view on Computer Vision problems, we
adopt an extended definition of the "interpretation" task (closed
to what was denoted as "high-level scene interpretation" [ 65]): it
consists in the construction of a symbolic description including
scene elements (objects or higher-level entities) and predicates.
(class memberships and
spatial relationships between
these elements). This extension, which implicitly bear prior
knowledge about
spatial relations, allows the acquisition of a new
kind of knowledge (the semantic content), concerning the possible
regular patterns of objects
spatial distributions. Furthermore, by
defining a
spatial description language as the set of models and
spatial relationships, the shortest description of the scene in
this language (in terms of existing objects and
spatial relations
between) defines the concept of optimal scene interpretation.
Actually, even if the storage is not a problem anymore and tools
for visualizing, streaming and interacting with 3D objects are
readily available, there is still a big lack of methods for coding,
extracting and sharing the semantic content of 3D media. Therefore,
the overall goal addressed by this thesis is the development of a
flexible approach (including framework, methodology, processing
methods and finally a working system) that could help us to extract
the semantic information of a
spatial scene. A lot of work related
to this idea has been done but most of it was dedicated to
geographic information systems (GIS). The…

▼ Although interacting with objects appears to
compress
spatial memory, the full extent of this effect is unknown.
To address this issue, I examined whether action-based compression
could extend to surrounding objects or environments. Participants
examined objects in two nested regions and recalled object-pair
distances for each region. In one region, participants inspected
objects manually or visually. In the other region, they only
inspected objects visually. By having participants interact with a
subset of objects, I assessed whether interaction compresses memory
for other objects. By marking the boundary between regions, I also
assessed whether interaction compresses memory for other
environments. When the boundary was unmarked, manual interaction
led participants to recall shorter distances throughout the
environment. However, marking the boundary led participants to
recall shorter distances overall. While these findings suggest that
manual interaction can compress
spatial memory throughout an
environment, the effects of interaction across environments remain
inconclusive.

▼ This thesis is concerned with the sense of self motion and orientation and how auditory cues from the surrounding soundscape contribute to these senses. It is known that vestibular, podokinetic and visual systems all contribute to our sense of self-motion in space and each provides the brain with different qualitative information in different reference frames. Sound exists all around us and human beings are highly accurate in localising the source of specific sounds. However, the contribution that hearing makes to human self-motion perception remains largely unexplored. The aim of this work was to explore how sound alters our perception of movement and how well a rotating soundscape can evoke audiokinetic vection; i.e. a sensation of rotation while stationary. The effects of sound on the vestibulo-ocular reflex (VOR) and the perception of movement are examined in chapter 2. Compared with silence and
subject-fixed sound, room-fixed sound prolonged both the VOR and perception of movement during constant velocity rotation but in a speed-dependent and idiosyncratic way. Chapter 3 describes the development of a novel means of delivering an audiokinetic stimulus to stationary subjects to simulate what an individual would hear during actual rotation in a stationary soundscape. Chapters 4 and 5 are concerned with the illusion of rotation caused by a moving auditory environment. Chapter 4 uses the stimulus method developed to study audiokinetic vection – the illusion of motion generated by rotating the entire auditory “scene” around a
subject. Healthy adult subjects were presented with a rotating auditory stimulus and reported feeling the sensation of self-motion at speeds similar to those reported with visual stimuli. Eye movements associated with audiokinetic vection are described in chapter 5. Subjects shifted gaze in the direction of perceived rotation, as is often observed during real movement. However, the slow eye movements that usually stabilise vision during motion were not observed. Chapter 6 concludes that sound does affect how human beings perceive self-motion but is given a lesser importance than other sensations.

▼ The present study investigated whether the perceptual simplicity of the objects depicting relations could facilitate young children's performance on a
spatial analogies task. In Study 1, children of 3 to 5 years (N = 120) were asked to generalize
spatial relations to instances comprised of a novel type of objects (cross-type generalization). Children were randomly assigned to generalize
spatial relations either from a schematic sample image (i.e., geometric shapes) to three rich choice images (i.e., line drawings of realistic objects) or from a rich sample image to three schematic choice images. Children across age performed better with the schematic samples than with rich samples. Study 2 examined generalization of
spatial relations to instances comprised of similar types of objects, in children of the same age range (N = 121). In this within-type generalization test, only 5year-old children, but not 3- or 4-year-old children, benefited from the schematic samples. The results overall indicate that perceptually simple objects are more effective in facilitating young children's generalization of
spatial relations than perceptually rich objects. Additionally, across both studies, young children's
spatial vocabulary, especially their acquisition of locative terms, was positively associated with their
spatial analogy skills, suggesting an intimate link between particular
spatial words and
spatial analogies. Keywords:
spatial analogies, generalization, object features, relational learning,

Malaria is a serious health threat in the World, mostly in Africa, where it has been
estimated that 90% of the world's cases occur (WHO, 2008). In Tanzania, close to
93% of the 34.4 million inhabitants are at risk of contracting the disease (PMI, 2005).
According to (Tanzania-Ministry of Health, 2008) the number of morbidity and
mortality among outpatient and inpatient admissions accounts for up to 40 percent.
The aim of this work is to generate useful spatial information to support decision
making concerning malaria control and monitoring in Tanzania.
Several multi-scale maps and graphics showing the most affected areas and
associated indicators which are favorable to mosquito densities through analyzed
data are shown, and suggestions focused on that analysis are given.
The results have shown that the households with bed nets for sleeping, those who are
spraying against malaria and those who are using insecticide mosquito bed nets are at
low risk of contracting malaria disease.

▼ Anatomy is the foundation to most medical disciplines, and a sound understanding is required to underpin many aspects ranging from routine physical examination to complex surgical procedures. For qualified veterinary surgeons, anatomy knowledge is pivotal. The vast number of species dealt with, along with the fact that immediately after graduation veterinary graduates are permitted as a 'Day One' competency to perform surgical procedures further emphasises the necessity for strong anatomy knowledge. Anatomy by its very nature is a spatial subject; the human or animal body lives in a three-dimensional space and is, in itself, three-dimensional. It requires the mental manipulation of complex structures and an understanding of their topographical relationships. This spatially demanding aspect of anatomy is challenging to veterinary students, yet, despite the importance of the subject and the known challenges of learning anatomy, limited studies have researched the possible relationship of spatial ability to anatomy learning in veterinary medical students. The overall aim of this project was to investigate the possible relationship of spatial ability to the learning of anatomy, and the influence of different teaching methods on this learning in first-year veterinary medical students. Three well-validated tests of spatial ability (Card Rotation Test, Mental Rotation Test, and Surface Development Test) were given to four cohorts of undergraduate first-year students. Of the four cohorts, two cohorts were first-year veterinary medical students from the same academic institution but different academic year (University of Edinburgh first-year veterinary medical students cohort 1 (UoE Vet 1) and cohort 2 (UoE Vet 2)), one cohort of first-year veterinary medical students from a different academic institution to allow for between academic institution comparisons (University of Bristol first-year veterinary medical students (UoB Vet)), and lastly, one control cohort of first-year students studying psychology (University of Edinburgh first-year psychology students (UoE Psych)) to account for the re-test effect. All four cohorts were given the exact same spatial ability tests at the start of the academic year and 15-16 weeks later. The cohorts UoE Vet 1 and UoE Vet 2 additionally received a two-dimensional teaching method and a novel three-dimensional spatial teaching method respectively, and scores on an in-course spatial MCQ assessment and their end-of-course examinations were collected for comparison. The first study of this project aimed to investigate the baseline spatial ability of veterinary students to assess how consistent this ability is within one academic institution (UoE Vet 1 and UoE Vet 2), across institutions (UoB Vet), and to a control cohort of students who do not learn anatomy (UoE Psych). The second study compared a two-dimensional teaching method (UoE Vet 1) to a novel teaching method purposefully designed to teach anatomy spatially (UoE Vet 2), with the aim of improving anatomy knowledge and understanding.

▼ In order to account for
spatial correlation in residuals in regression models for areal and lattice data, different disciplines have developed distinct approaches. Bayesian
spatial statistics typically has used a Gaussian conditional autoregressive (CAR) prior on random effects, while geographers utilize Moran's I statistic as a measure of
spatial autocorrelation and the basis for creating
spatial models. Recent work in both fields has recognized and built on a common feature of the two approaches, specifically the implicit or explicit incorporation into the linear predictor of eigenvectors of a matrix representing the
spatial neighborhood structure. The inclusion of appropriate choices of these vectors effectively reduces the
spatial autocorrelation found in the residuals. We begin with extensive simulation studies to compare Bayesian CAR models, Restricted
Spatial Regression (RSR), Bayesian
Spatial Filtering (BSF), and Eigenvector
Spatial Filtering (ESF) with respect to estimation of fixed-effect coefficients, prediction, and reduction of residual
spatial autocorrelation. The latter three models incorporate the neighborhood structure of the data through the eigenvectors of a Moran operator. We propose an alternative selection algorithm for all candidate predictors that avoids the ad hoc approach of RSR and selects on both model fit and reduction of autocorrelation in the residuals. The algorithm depends on the marginal posterior density a quantity that measures what proportion of the total variance can be explained by the measurement error. The algorithm selects candidate predictors that lead to a high probability that this quantity is large in addition to having large marginal posterior inclusion probabilities (PIP) according to model fit. Two methods were constructed. The first is based on orthogonalizing all of the candidate predictors while the second can be applied to the design matrix of candidate predictors without orthogonalization. Our algorithm was applied to the same simulated data that compared the RSR, BSF and ESF models. Although our algorithm performs similarly to the established methods, the first of our selection methods shows an improvement in execution time. In addition, our approach is a statistically sound, fully Bayesian method.

▼ Spatial Modeling has been one of the important parts in Applied Econometrics as well as Econometrics Theory in the past thirty years, not only because of the nature that the geographic locations and interactions play a crucial role in forming behavior, but also because of the challenging problems inherited from
spatial dependence in Econometric models. Misspecifications of
spatial dependence in regression models lead to misleading inferences and policy implications.
In this dissertation I focus on issues of model specification tests which arise from the
spatial structures of the data, and it contributes to the
Spatial Econometric literature in two ways: first, the important consequences of misspecified
spatial dependence in estimation, hypothesis testing, and calculation of impact effects, and second, the methodologies for non-standard tests in
spatial regression models. I provide both econometric methods and empirical examples to demonstrate the usefulness of the proposed testing procedures.
In chapter 1 I study the behavior of standard and adjusted Rao score (RS) tests for
spatial dependence in presence of negative
spatial dependence. I found that the power of the standard test can be very low when there is negative
spatial dependence. I also compared the features of negative autocorrelation between the time series and
spatial contexts. In time series case, both the pattern of variance-covariance matrices and the power curves are symmetric for positive and negative serial correlations. This symmetry, however, is not observed in the
spatial context. I applied my findings to the U.S. state government expenditure data, and found negative
spatial lag dependence in U.S. state government expenditure, suggesting competitions among the state governments [Saavedra (2000); Boarnet, Marlon and Glazer (2002)]. Consistent with my theoretical derivation, the standard RS test is misleading, and under the negative
spatial dependence, the values and interpretation of impact effects are also different.
When incorporating
spatial dependence, the most common specification is a
spatial autoregressive (AR) process, either in the dependent variable or disturbances. However, as argued in Anselin (2003), in many cases a
spatial moving average (MA) is more appropriate if the mechanism of interest is a localized
spatial spillover. In chapter 2 I consider the problem of testing no
spatial dependence against a
spatial autoregressive and moving average (ARMA) process, which allows for a global direct
spatial effect in the dependent variable as well as an unobserved or indirect local
spatial effect. I suggest a test procedure and the simulation results show that the proposed test has desired size and good power performance.
In chapter 3, I further study the problems of testing no
spatial dependence against a
spatial ARMA process in the disturbances, in the presence of
spatial lag dependence. The problems of conducting such a test are twofold. First, under the null hypothesis of no
spatial dependence in the disturbances,…

▼ The second generation of the Landscape Disturbance and
Succession model (LANDIS-II) is frequently used to understand
ecological succession on the landscape. LANDIS-II is an important
simulation tool but it can be difficult to parameterize properly in
data-poor regions. By examining the
spatial sensitivity of
LANDIS-II, the model’s users will have an improved understanding of
the data required to properly implement the model. Existing studies
have tested the ecological sensitivity of LANDIS-II in local
geographic settings, but a robust test of the model's
spatial
sensitivity has not been completed. This research tested the
spatial sensitivity of the LANDIS-II spatially stochastic landscape
model using a broad set of vegetation communities found within the
contiguous United States. Thirty spatially explicit, equal-area,
and area-weighted iterations of the
spatial parameters of the
LANDIS-II model were run for a series of localities in the
contiguous United States, where the areas were defined by the
spatial composition of vegetation community values. Ecological
attributes were derived from the NatureServe Ecological Systems of
the United States dataset. A test of the
spatial input parameters
of LANDIS-II demonstrated that the model is aspatial under certain
conditions. Furthermore, vegetation community interactions may be
effectively represented in LANDIS-II by a series of spatially
stochastic input rasters; such that assessing a locality’s
vegetation trend is possible even when spatially explicit land
classification information is unavailable, thereby facilitating
long-term environmental planning in data-poor
environments.

▼ Grid cells, defined by their strikingly periodic
spatial responses in open fields, have spurred widespread theoretical interest, and numerous models have been proposed to explain how grids are formed, how they are differentiated from the others, and how they might use idiothetic (self motion) information to path integrate. This dissertation leverages unique grid cell data together with computational and mathematical approaches to unravel grid cell dynamics and structure during navigation in general. First, we analyze several extensive datasets of grid cells recorded in 2-dimensional (2D) environments under a number of experimental manipulations, and show that the multi-dimensional network activity of grid cells is embedded into a two-dimensional continuous attractor manifold. Second, we analyze grid cell responses on linear 1-dimensional (1D) tracks to extract an underlying 2D grid structure. Combining Fourier analytical methods and numerical refinements, we show that the system remains in the same dynamical regime during navigation in 2D and 1D environments. Finally, we introduce a state-space point process filter to track the temporal evolution of
spatial tuning curves and examine the error accumulation of grid cell system. We show that we can accurately infer the drift of the internal estimate of positions subsumed in the grid cell system as a path integrator.

▼ Data warehousing and On-line Analytical Processing
(OLAP) are powerful tools for processing and analyzing business and
analytical data. It is estimated that 80% of the data stored in
data warehouses have some
spatial components. It is our belief that
there is a need for powerful OLAP tools that are capable of
processing and analyzing
spatial data. This thesis explores the
design and implementation of
Spatial OLAP (SOLAP) systems and
describes approaches to support the characteristic features of OLAP
while seamlessly integrating
spatial data into the analysis
process. In particular, we analyze the evaluation of OLAP queries
in the presence of asymmetric, multiple-alternative, generalized,
and non-strict
spatial dimension hierarchies. We introduce a new
pipeline-based query evaluation model that is comprehensive and
powerful in that it provides a uniform approach to the expression
of
spatial OLAP queries that address all major dimension hierarchy
types while permitting a uniform treatment of both
spatial and
non-
spatial data. A reference implementation called "LISA"
validates the objectives of our model and demonstrates favorable
scalability and performance on modern multi-processor and
multi-core hardware platforms. We also describe a new "geoCUBE"
index, to address the fundamental problem of how to represent,
index and efficiently query data that is defined by a mix of
spatial and categorical attribute values. The geoCUBE index extends
existing methods for indexing OLAP data to
spatial data types. The
effectiveness of the geoCUBE data structure is confirmed through
evaluation. Lastly, we propose algorithms that facilitate OLAP-like
analysis of moving object data. We introduce a new class of GROUP
BY operators specifically targeted to the OLAP analysis of
trajectories and to answering aggregate queries with respect to the
spatio-temporal movement of a set of objects. Through an
experimental evaluation we show our operators can be used to
reliably identify groups of related trajectories when applied to
synthetic and real world moving object data.

▼ The world-wide earthquake locator is an online mapping application that maps the location and severity of earthquakes which have occurred since 1970`s. The current mapping system the site is using is beginning to look dated and there is an opportunity to update the display using a Google maps mash-up. This would display the data from The U.S geological survey in a modern manner that is consistent with current online mapping trends.
A new visual representation of the USGS information would hopefully allow trends and patterns within the data to be identified. Modernising the map using open source tools such as the Google Ajax API, KML, Perl scripts and Oracle RDBMS should improve the experience for the user and allow them to learn more about the distribution of larger earthquakes.
Analysis of databases and the data infrastructure will be required in order to ascertain why certain aspects of the site currently do not function.

▼ Psychology
The ability to recall a spatial layout from multiple orientations – spatial flexibility – is a challenging cognitive process, especially when the global configuration cannot be viewed from a single vantage point, as spatial information must first be integrated before it can be flexibly recalled. The current study examined if experiencing the transition between multiple viewpoints enhances spatial flexibility for both non-integrated (Exp. 1) and integrated environments (Exp. 2), if the type of transition matters, and if action provides an additional advantage over passive visual flow. In Experiment 1, participants viewed an array of dollhouse furniture from four viewpoints that presented the global configuration from multiple orientations. In Experiment 2, the array was viewed piecemeal, from four viewpoints that presented the global configuration in partial chunks. The control condition presented the dollhouse as a series of static views, whereas in the remaining conditions, visual flow was continuous. Participants viewed the natural transition between viewpoints, and either passively experienced the transitions (i.e., by watching the dollhouse rotate or being rolled around it), or actively generated them (i.e., by rotating the dollhouse or walking around it). Across both experiments, continuous visual flow significantly enhanced spatial flexibility when paired with observer movement around the dollhouse, either active or passive. Furthermore, when participants had to integrate spatial information across discrete learning experiences (Exp. 2), active movement provided a significant advantage above passive experience. These findings suggest that array stability is key to flexible spatial memory, with action providing an additional boost to spatial integration.

▼ Prior research has uncovered a close coupling of
spatial attention to sensori-motor processes both anatomically and in function. The outstanding question investigated in this research was whether the evident coupling between
spatial attention and sensori-motor processes was dissociable. Neural correlates of
spatial attention and oculomotor preparation were investigated using event-related potentials (ERP) elicited by a symbolic cue in four different experimental conditions: same side, opposite side, attention, and oculomotor. The crucial test to dissociate the links between
spatial attention and oculomotor preparation processes was the simultaneous cuing of each process to opposite sides of space. As expected, ERP components found in the same side, attention, and oculomotor conditions were entirely absent in the opposite side condition. Interpreted in the framework of the premotor theory of attention (Rizzolatti et al., 1994), this investigation supports an argument for mandatory links between
spatial attention and oculomotor preparation.

▼ Dissertation submitted in partial fulfillment of the requirements for the Degree of Master of Science in Geospatial Technologies.
Sketch-based spatial query systems provide an intuitive method of user interaction for
spatial databases. These systems must be capable of interpreting user sketches in a way
that matches the information that the user intended to provide. One challenge that must be
overcome is that humans always simplify the environments they have experienced and this
is reflected in the sketches they draw. One such simplification is manifested as aggregation
or combination of spatial objects into conceptually or spatially related groups.
In this thesis I develop a system that uses reasoning tools of the RCC-8 to evaluate sketchbased
queries and provide a method for minimizing the effects of aggregation by
determining whether a solution to a query can be expanded if some groups of regions are
assumed to be parts of a larger aggregate region. If such a group of regions is found, then
this group must be included in the solution. The solution is approximate because the
approach taken only verifies that assumed parts of an aggregate are not inconsistent with
the configuration of the whole solution. Only cases where the size of the solution equals the
size of the query minus one are analysed.
It is observed that correctly identifying aggregated regions leads to solutions that are more
similar to the original query sketch when the size of every other solution is smaller than the
size of the query or when a lower limit is placed on the acceptable size of a solution because
the new, expanded or refined solution becomes more complete with respect to the sketch
of the query.

▼ With the explosive increase of the amount of information in recent years, the research on the big data has become an inevitable topic of the research. How to mine the information which we are interested in and use it a lot will become a really important and necessary issue. Looking for the
spatial co-location pattern that appears frequently nearby over an incremental database also becomes an interesting and essential topic. An incremental database refers to the fact that the entire database becomes larger after the data has been inserted or deleted over time in the original database. It can be widely used in many areas due to the changes in data over time, including the location-based services (LBS), environmental ecology, and also the business behavior patterns. In this project, we only consider the insertion of the data. Many
spatial co-location pattern mining approaches are for traditional
spatial databases. Therefore, they do not need to consider candidate instances generated and update their participation index in the process. Yoo et al. have proposed the EUCOLOC algorithm to mine co-location patterns in the incremental database. This method may record the duplicated data both in the original database and the incremental database during inserting the new data. They generate many candidate instances, and then delete some of these candidate instances by checking whether their subsets exist or not. Finally, they update the participation index in the process and update co-location patterns. However, this method not only needs large storage to store points in the database and their relationships with each other, but also generates many unnecessary candidate instances (eg, non-incremental candidate instances). In this project, we plan to propose the non-overlapping approach to mine the colocation patterns for incremental database. The non-overlapping algorithm refers to the situation that can avoid duplicated edges recorded in the original and incremental database. In other words, no edge will be recorded in the original database when it is recorded in the incremental database. First, we plan to propose approach that rearrange the relations by the asterisk annotation priority in order to use less storage to store data information and also can avoid generating the non-incremental candidate instances. Second, we plan to check the relation of the subset before generating size-k candidate instances. In this way, we can avoid generating non-clique instances completely. Therefore, our method, which expect to avoid generating non-incremental candidate instances and non-clique candidate instances, as well as to avoid storing duplicate data, resulting in better performance of
spatial co-location pattern mining.

▼ When spatial updating tasks are performed in a real-world setting, participants usually complete it with ease (e.g., Klatzky et al., 1998). However, in virtual reality (VR), when tasks are presented using optic flow, participants tend to exhibit one of two response patterns, with some participants correctly updating their headings (“turners”) and others pointing consistently in the opposite direction (“non-turners”) (e.g., Gramann et al., 2005). While research has looked at the stability and pointing characteristics of these two groups (e.g., Gramann et al., 2012; Riecke, 2008), we still do not know why non-turners exist. The following thesis studied two potential sources of cue conflict—stationary versus central visual information and sensorimotor interference—that could impact participants’ strategies using the Starfield task (Gramann et al., 2012). Occluding stationary peripheral information increased pointing errors, especially for turners. It is thus possible that turners require the peripheral information to correctly parse and process the central optic flow. Alternatively, manipulating body orientation to decrease sensorimotor interference seemed to decrease error and increase strategy consistency for both turners and non-turners. It is possible that the orientation changes allowed participants to ignore the stationary body- based cues, thereby improving spatial updating. Although these manipulations did not remove the non-turner group altogether, they provided important insights into how cue conflicts may play a role in spatial updating for VR tasks.

▼ Climate change and competing land use needs continue to drive change in forest management in British Columbia. Balancing these needs in the face of a diminishing timber harvesting land base presents ongoing challenges for forest managers. This is especially true for small, area based tenures. Overlapping or competing land use values, such as Species at Risk habitat, can have a disproportionate effect on their management and viability. While government and industry processes exist for optimizing competing objectives while still managing for timber, they are largely tailored at a scale and magnitude suited to major industry and not small area-based tenures. This case study explores the potential of adapting one such process, the Stewardship/Timber Harvesting Landbase (THLB) Stabilization Pilot process, to small tenures using spatial modelling. Focusing on a Woodlot Licence in the Fraser Valley, predictive habitat models were developed for two Species at Risk using readily available software and data. Although spatial correlation of model results with known habitat reserves was inconclusive, models show promise as cost-effective tools for small tenure managers to visualize ecosystem values and their management implications.

▼ The concept of extreme events describes the above
average behavior of a process, for instance, heat waves in climate
or weather research, earthquakes in geology and financial crashes
in economics. It is significant to study the behavior of extremes,
in order to reduce their negative impacts. Key objectives include
the identification of the appropriate mathematical/statistical
model, description of the underlying dependence structure in the
multivariate or the
spatial case, and the investigation of the most
relevant external factors. Extreme value analysis (EVA), based on
Extreme Value Theory, provides the necessary statistical tools.
Assuming that all relevant covariates are known and observed, EVA
often deploys statistical regression analysis to study the changes
in the model parameters. Modeling of the dependence structure
implies a priori assumptions such as Gaussian, locally stationary
or isotropic behavior. Based on EVA and advanced time-series
analysis methodology, this thesis introduces a semiparametric,
nonstationary and non- homogenous framework for statistical
regression analysis of spatio-temporal extremes. The involved
regression analysis accounts explicitly for systematically missing
covariates; their influence was reduced to an additive
nonstationary offset. The nonstationarity was resolved by the
Finite Element Time Series Analysis Methodology (FEM). FEM
approximates the underlying nonstationarity by a set of locally
stationary models and a nonstationary hidden switching process with
bounded variation (BV). The resulting FEM-BV- EVA approach goes
beyond a priori assumptions of standard methods based, for
instance, on Bayesian statistics, Hidden Markov Models or Local
Kernel Smoothing. The multivariate/
spatial extension of FEM-BV-EVA
describes the underlying
spatial variability by the model
parameters, referring to hierarchical modeling. The spatio-temporal
behavior of the model parameters was approximated by locally
stationary models and a
spatial nonstationary switching process.
Further, it was shown that the resulting
spatial FEM-BV-EVA
formulation is consistent with the max-stability postulate and
describes the underlying dependence structure in a nonparametric
way. The proposed FEM-BV-EVA methodology was integrated into the
existent FEM MATLAB toolbox. The FEM-BV-EVA framework is
computationally efficient as it deploys gradient free MCMC based
optimization methods and numerical solvers for constrained, large,
structured quadratic and linear problems. In order to demonstrate
its performance, FEM-BV-EVA was applied to various test-cases and
real-data and compared to standard methods. It was shown that
parametric approaches lead to biased results if significant
covariates are unresolved. Comparison to nonparametric methods
based on smoothing regression revealed their weakness, the locality
property and the inability to resolve discontinuous functions.
Spatial FEM-BV-EVA was applied to study the dynamics of extreme
precipitation over Switzerland. The analysis identified among
others three major…

▼ This study investigated the effect that participation in basketball had on the spatial abilities of high school students. Many studies have examined differences in spatial abilities related to gender and have also examined differences in the spatial abilities between athletes and non-athletes at the collegiate level (Rossi, 1979 and Lord & Leonard, 1997). The inventory used in this study was created in an effort to find any differences that might exist between non-athlete students and student-athletes. The inventory consisted of questions dealing with pattern determination, olding, rotating, mental block manipulation and assembly of three-dimensional objects. The inventory also contained a student questionnaire used to determine the amount of time the students spent in organized sports, playing sports on their own, number of years playing basketball and number of seasons the student participated in sports at school. A total of 154 students that included 48 basketball players and 106 non-basketball players completed this inventory. In this study, students were designated as a basketball player if they played three or more years of basketball. Basketball was chosen because it is a sport that requires manipulation of a sphere, and the constant awareness of an ever-changing three-dimensional environment. Results suggest that the basketball players have greater spatial abilities than the non-basketball players. Additionally, the mean score of students who participate in two to three seasons was significantly greater than the students who participate in one or fewer seasons. However, there was no significant difference found between genders in this study.

▼ The purpose of this investigation was to determine if there was a correlation between participation in organized sports and a student's spatial reasoning ability in recognition of transformations of geometric figures. This study also attempted to identify which sports, if any, had that correlation. A sample of three hundred fifty-seven grade 9 and grade 10 students from a public school in a middle class suburban town in central Connecticut were used in this study. The participants completed a sports participation questionnaire and spatial reasoning assessment. The researcher then analyzed the results using analysis of variance (ANOVA), T-Test and Two-Sample T-Test. The study found that although the mean score of the athletes was higher than that of the non-athletes it was not considered to be statistically significant. Another finding in this study was that the top three sports that students participated in that had higher spatial reasoning scores were lacrosse, track and volleyball. In addition, the top three sports that students participated in that had lower spatial reasoning scores were cheerleading, field hockey and hockey. However, these findings were also not considered statistically significant. The only statistically significant finding from this study was that the male students outscored female students on the spatial reasoning assessment regardless of sports participation.

▼ The objective of this dissertation is to extend the use of
spatial predictive modelling for use by biosecurity agencies to help prevent the introductions of new and emerging invasive plants (i.e., pests). A critical review of international and national policy instruments found that they did not effectively articulate how
spatial predictive modelling could be incorporated into the biosecurity toolbox. To determine how
spatial predictive modelling could be extended I modelled the potential distribution of Tamarix and Lythrum salicaria in Prairie Canada using a genetic algorithm. New seasonal growth data was used to interpolate a growing degree-day’s risk surface for L. salicaria. Models were developed using suites of predictive variables as well as different data partitioning methods and evaluated using different performance measures. Expert evaluation was found to important in final model selection. The results indicated that both invasive plants have yet to reach their potential distribution in Prairie Canada. The
spatial models can be used to direct risk-based surveillance efforts and to support biosecurity policy decisions. The results of this dissertation conclude that
spatial predictive modelling is an informative tool that needs to be incorporated into the biosecurity toolbox. A phytosanitary standard is proposed to guide toolbox development.

▼ The study investigates spatial orientation in Ga, two frameworks were adopted for this work namely; Cognitive Semantics and grammaticalization. Cognitive semantics attaches more importance to conceptual structure and our embodied experience and also deals with extended meanings while grammaticalization accounts for meaning related to body parts, time and other grammatical notions. The main methodology adopted for this study is the Topological Relation Picture Series (TRPS), the (1993) edition designed by Penelope Brown and Eric Pederson. The aim of the work is to present comprehensive analyses of Spatial Orientation in Ga from the cognitive linguistics perspective. Looking at the the similarities and differences which are expressed in the language.
Speakers of Ga have ways of locating entities in the language using specific spatial concepts. Spatial concepts indicate the exact location of objects. Svorou (1994), writes that most spatial concepts are derived from human body parts. The body part terms are grammaticalized and are used as spatial concepts in Ga. The study also discusses some conditions necessary for grammaticalization. The conditions for grammaticalization include phonetic bleaching, semantic force, frequency of form, pragmatics influence and conceptual strategies. The study also examines non-metaphorical and metaphorical use of body part terms in Ga. Metaphorical use of body part terms were discussed under three major headings namely: Face and its parts- yitso „head‟, hiŋmɛi „eye‟ and naabu „mouth‟, Internal parts- tsui „heart‟, musu „stomach‟ and Intangible part- jwɛŋmɔ „mind‟. Metaphorical use of body parts terms was discussed with reference to metaphor and metonymy which are used in everyday language.
The study further explores positional verbs in Ga. “Positional verbs” is used in this thesis as a cover term that refers to a class of verbs that semantically encode the static assumed body posture or position of animate entities such as humans and animals or the static location of inanimates (objects) in space. The study discusses Ga data in the context of cross-linguistic studies on posture, positional and locative verbs (Newman, 2002a; Levinson & Wilkins 2006a, Ameka & Levinson 2007a). Languages use verbs to describe a wide range of semantic notions involving different locative relations between the Figure and the Ground such as body position, elevation, attachment, containment, and distribution. The findings of the study are that positional verbs such as damɔ „to stand‟ are used for humans and inanimate objects whereas ma „to stand‟ is used for inanimate entities and ka „to lie‟ is used for both animates and inanimate objects. Again, yɛ „be at‟ is a general verb used to describe animate and inanimate objects in the language.
