▼ Accurate measures of forest structural parameters are essential to forest inventory and growth models, managing wildfires, and modeling of carbon cycle. Terrestrial laser scanning (TLS) provides accurate understory information rapidly through non-destructive methods. This study developed algorithms to extract individual tree height, diameter at breast height (DBH), and crown width in plots at Ecosystem Science and Management (ESSM) research area and Huntsville, Texas. Further, the influence of scan settings and processing choices on the accuracy of deriving tree measurements was also investigated. The study also developed models to estimate aboveground biomass (AGB) and investigate different conceptual approaches to study tree level growth in forest structural parameters and AGB using multi-temporal TLS datasets. DBH was retrieved by cylinder fitting at different height bins. Individual trees were extracted from the TLS point cloud to determine tree heights and crown widths. The R-squared value ranged from 0.91 to 0.97 when field measured DBH was validated against TLS derived DBH using different methods. An accuracy of 92% was obtained for predicting tree heights. The R-squared value was 0.84 and RMSE was 1.08 m when TLS derived crown widths were validated using field measured crown widths. Examples of underestimations of field measured forest structural parameters due to tree shadowing have also been discussed in this study. Correction factors should be applied or multiple high resolution scans should be conducted to reduce the errors in estimation of forest structural parameters. TLS geometric and statistical parameters were derived for individual trees and used as explanatory variables to estimate AGB. An extensive literature review reveals that this is the first study to model the change in AGB using different innovative and conceptual approaches with multi-temporal TLS data. Tree level AGB growth was studied over a period of three years using three different approaches. Results showed that TLS derived geometric parameters were better correlated to field measured AGB. Promising results for AGB change were obtained using the direct modeling approach; hence forest growth could be studied independent of any field measurements when biomass models are available. However, the models could be improved by incorporating more trees with a wide range of DBH and tree heights. The results from this study will benefit foresters, planners, and other remote sensing studies from airborne and spaceborne platforms, for map upscaling, data fusion, or calibration purposes.

Research Doctorate - Doctor of Philosophy (PhD)

Lithography is the process of selectively exposing optically sensitive materials during semiconductor fabrication. One issue with standard projection lithography is the high cost of infrastructure and mask sets. These costs may be prohibitively expensive for prototyping and low-volume production. Scanning-beam lithography methods are attractive alternatives to projection lithography for low-volume applications. These methods include scanning electron-beam, ion-beam, and scanning optical lithography. This thesis aims to maximize the resolution of scanning lithography methods by model-based optimization of the exposure pattern. Scanning laser lithography is used as an example process; however, the proposed methods are applicable to a wide range of serial fabrication processes. The exposure pattern in a scanning lithography system describes the energy delivered versus the spatial coordinates. For a positive photoresist areas that receive an exposure dosage above a threshold are dissolved during development. The surface dosage is described as a two dimensional convolution of the exposure pattern with the beam profile. This thesis presents three methods for the optimization of exposure patterns. The first method casts the problem as a constrained non-linear optimization. This problem is then solved iteratively using an interior-point method. The second method involves a direct gradient-based search with an analytical gradient calculation and step-size approximation. Both methods converge to similar solutions; however, the interior point method requires less iterations, and the gradient-based method requires significantly less memory. The third proposed method interprets the process model as a constrained non-linear convolution. An exposure pattern is then derived by employing an iterative deconvolution method. This method requires the least computational resources. However, the deconvolution method does not explicitly minimize a cost function; therefore, it is difficult to explicitly penalize variables such as the total exposure energy. The performance of each proposed method is assessed through simulation and experimental results. The thesis is concluded by a comparison of the three methods using metrics including the minimum feature error, computational requirements, and the number of non-zero exposures.

▼ Terrestrial laser scanning (TLS) techniques have proven to be efficient to collect three-dimensional high-density and high-accuracy point clouds for coastal research and resource management. LiDAR-based bare-earth digital elevation models (DEMs) are widely used for quantification analysis of beach and dune morphological changes in time and space. This study aims to quantify the morphological changes in the vicinity of the Brazos River delta in Freeport, Texas during the period from summer of 2015 to winter of 2016 using the TLS and GPS integrated techniques. TLS collects a massive amount of surveying points. The processing and presentation of the large volumes of datasets is always a challenge for research when targeting large areas. This study developed a practical workflow for TLS data acquisition and massive data processing, and for the analysis of digital elevation models (DEMs) aimed to derive coastal morphological changes. Four repeated TLS datasets were collected in May and December of 2015, and May and December of 2016. Four high-resolution DEMs were generated following the workflow introduced in this study. The changes of shoreline, vegetation line, dune ridge, volume, and beach profiles were investigated by utilizing the high-resolution and highly accurate DEMs. The final analysis and visualization of results were completed using ArcGIS. Results from this study indicate that significant beach erosion happened since the summer of 2015 to the winter of 2016. The short-term rate-of-change and net movement are higher than those calculated in previous long-term studies in the Freeport beach region. On average, the shoreline retreated 15.6 m since May 2015 to December of 2016. The change of the dune ridge is minor. However, the changes of vegetation line and dune volume are significant. The short-term rapid topographic change in the Freeport beach and dune was caused mainly by several storm flood events that affected the Texas coast in May of 2015 and April of 2016. It is expected that this study will promote the applications of the GPS and TLS techniques in coastal erosion and other natural hazards studies in Texas and other natural hazard-prone areas.

▼ This thesis presents a case study on beach growth of a South Holland beach located slightly north of the Sand Motor over the course of six months, which was measured using a terrestrial laser scanner (TLS). This device was set up to continuously take hourly full coverage measurements of a one kilometre stretch of beach from a hotel rooftop. As sea-levels rise, interest in the morphological processes that take place on beaches is growing, so that coastal safety can be continued to be guaranteed in the future. As a result, it becomes increasingly relevant to understand the transport of sediment towards the beach. Existing studies on the subject focus on timescales of years to decades, often making use of GPS measurements. However, no thorough research has been performed on sub-annual timescales in over a decade, leading to the following main research question for this thesis: How is beach volume growth distributed on sub-annual time scale, both in spatial and temporal dimensions? To validate the data obtained by the TLS, an accuracy check was performed which proved the standard deviation of the measurements to be much smaller than the observed morphological change. A rotational instability of the scanning device was discovered and corrected, however a higher measurement accuracy could be obtained by developing a more detailed correction method. The applied correction method did however no longer allow for the study of smaller fluxes such as aeolian transport, as they are overruled by it. It was investigated how the raw 3D data obtained from the TLS should be processed to obtain a clean timeseries of cross-sections. A framework is presented that includes noise detection and removal, object filtering, interpolation and subsampling. Subsequently, timeseries of 132 cross-sections were extracted from the data by selecting a daily low tide scan for 132 days along 4 different transects. The resulting timeseries clearly display morphological activity such as intertidal bar migration and storm erosion, and volumetric computations have displayed periods of beach growth. These periods generally occur between storms, during calm wind and wave conditions. The main driver for this growth is the onshore migration of intertidal bars. As bars enter the intertidal zone, they migrate onshore and grow, increasing the volume of the beach. A swash bar that formed high in the intertidal zone during neap tide was found to migrate at increased rate during the neap-spring tidal cycle and welded to the beach, as compared to a different bar which migrated during the springneap cycle. Following spring tide, the bar ceased onshore migration and an offshore expansion occurred. This offshore expansion had a great effect on the volumetric growth of the total beach profile and showcases the influence of tide in the migration of swash bars. However, due to the great number of factors that influence beach growth, only few significant correlations were found between beach volume changes and boundary conditions such as… Advisors/Committee Members: Aarninkhof, Stefan (graduation committee), Vos, Sander (mentor), de Vries, Sierd (graduation committee), Lindenbergh, Roderik (graduation committee), Delft University of Technology (degree granting institution).

▼ The historic preservation field, enabled by advances in technology, has demonstrated an increased interest in digitizing cultural heritage sites and historic structures. Increases in software capabilities as well as greater affordability has fostered augmented use of digital documentation technologies for architectural heritage applications. Literature establishes four prominent categories of digital documentation tools for preservation: laser scanning, photogrammetry, multimedia geographic information systems (GIS) and three-dimensional modeling. Thoroughly explored through published case studies, the documentation techniques for recording heritage are most often integrated. Scholarly literature does not provide a parallel comparison of the four technologies. A comparative analysis of the four techniques, as presented in this thesis, makes it possible for cities to understand the most applicable technique for their preservation objectives. The thesis analyzes four cases studies that employ applications of the technologies: New Orleans Laser Scanning, University of Maryland Photogrammetry, Historic Columbia Maps Project and the Virtual Historic Savannah Project. Following this, the thesis undertakes a trial of each documentation technology – laser scanning, photogrammetry, multimedia GIS and three-dimensional modeling – utilizing a block on Church Street between Queen and Chalmers streets within the Charleston Historic District. The apparent outcomes of each of the four techniques is analyzed according to a series of parameters including: audience, application, efficacy in recordation, refinement, expertise required, manageability of the product, labor intensity and necessary institutional capacity. A concluding matrix quantifies the capability of each of the technologies in terms of the parameters. This method furnishes a parallel comparison of the techniques and their efficacy in architectural heritage documentation within mid-sized cities.

▼ Transportation agencies in many countries require high-accuracy (2-20 cm) digital terrain models (DTMs) along roads for various transportation related applications. Compared to traditional ground surveys and aerial photogrammetry, mobile laser scanning (MLS) has great potential for rapid acquisition of high-density and high-accuracy three-dimensional (3D) point clouds covering roadways. Such MLS point clouds can be used to generate high-accuracy DTMs in a cost-effective fashion. However, the large-volume, mixed-density and irregular-distribution of MLS points, as well as the complexity of the roadway environment, make DTM generation a very challenging task. In addition, most available software packages were originally developed for handling airborne laser scanning (ALS) point clouds, which cannot be directly used to process MLS point clouds. Therefore, methods and software tools to automatically generate DTMs along roads are urgently needed for transportation users. This thesis presents an applicable workflow to generate DTM from MLS point clouds. The entire strategy of DTM generation was divided into two main parts: removing non-ground points and interpolating ground points into gridded DTMs. First, a voxel-based upward growing algorithm was developed to effectively and accurately remove non-ground points. Then through a comparative study on four interpolation algorithms, namely Inverse Distance Weighted (IDW), Nearest Neighbour, Linear, and Natural Neighbours interpolation algorithms, the IDW interpolation algorithm was finally used to generate gridded DTMs due to its higher accuracy and higher computational efficiency. The obtained results demonstrated that the voxel-based upward growing algorithm is suitable for areas without steep terrain features. The average overall accuracy, correctness, and completeness values of this algorithm were 0.975, 0.980, and 0.986, respectively. In some cases, the overall accuracy can exceed 0.990. The results demonstrated that the semi-automated DTM generation method developed in this thesis was able to create DTMs with a centimetre-level grid size and 10 cm vertical accuracy using the MLS point clouds.

▼ Subsidence can be observed at various locations in the Netherlands. While it can be due to both shallow and deep subsurface processes, the shallow subsidence is mainly a result from compaction, oxidation and/or groundwater drainage. Moreover, for grasslands on organic soils, in particular pastures on drained peat soils, the vertical position of the ground level is subject to significant temporal variability. Temporal scales of the vertical motion are expected to vary between days and centuries, and spatial scales between millimeters and kilometers. Unfortunately, performing precise, reliable, and representative geodetic measurements of shallow subsidence processes is very difficult for soils, as fixed benchmarks do not exist. Here we propose an insitu measurement procedure for grass-covered soils using laser scanning, both terrestrial and airborne, using a vertically fixed reference platform. We show that for terrestrial laser scanning (TLS) it is possible to detect changes in the vertical position of soils with a systematic error of up to 2.6 mm and a standard deviation of 0.4 mm. Given a predefined level of significance of 훼 =0.05 (confidence level of 95%) and a detectability power of 훾 =90%, we achieve a minimal detectable vertical deformation (MDD) of 21.1 mm in our study area. We show that the results are influenced by the grass density and length, the incidence angle of the laser beam, as well as other settings of the laser scanner. We find that the parameter settings of the method for estimating soil surface, and subsequently the subsidence, has an influence on the results and related statistics. For airborne laser scanning (ALS), using a precisely leveled reference platform, we find that the quality of elevation estimates is still limited, requiring further considerations on the design of data acquisition surveys and the reference platforms. Our results demonstrate the ability of laser scanning technology for investigating shallow subsurface motion of grass-covered soils relative to a benchmark on a local scale. Based on the quality assessment, the detection of vertical ground level change is better understood in terms of time and probability. In future research, the factors affecting terrestrial laser scanning technology to accurately identify soils affected by vegetation, environment, and device condition, should be further studied.

Trabalho final de mestrado para obtenção do grau de mestre em Engenharia Biomédica

A comparação da digitalização 3D por fotogrametria com a digitalização 3D por varrimento por LASER permite avaliar a sua precisão relativa, visando concluir a possibilidade de aplicação em biomédica ou outras aplicações em que a precisão e rapidez de aquisição são necessárias. Para tal foi feito um estudo sobre estas duas tecnologias, após o qual foram realizados alguns testes práticos. Em termos práticos foram realizados vários conjuntos de fotografias em condições diferentes e foram também efetuadas digitalizações 3D através de varrimento por laser para obter um modelo de referência. Os objetos digitalizados foram um cubo e um modelo anatómico de um sacro. Com o auxilio de uma aplicação de reconstrução utilizada em fotogrametria (Autodesk ReMake), foram obtidos modelos com base nos conjuntos de fotografias realizados. Adicionalmente foram feitas medições com um paquímetro no cubo utilizado como modelo. As restantes medições foram feitas através de programa de manipulação de modelos 3D (Geomagic versão trial e Autodesk ReMake). Foi concluído que sem qualquer máquina dedicada para o auxilio no processo de fotogrametria e, por consequência, uma situação em que nem todas as condições foram controladas da melhor forma possível, obteve-se, nos casos mais favoráveis do sacro, um desvio padrão de 0,289 mm. Conclui-se, ainda, que modelos obtidos por fotogrametria mantêm as proporções, mas não mantêm a escala 1:1, em relação ao modelo real. Esta tecnologia tem um grande potencial em diferentes aplicações incluindo na engenharia Biomédica, na medida em que permite separar a etapa de aquisição da etapa de processamento das fotografias para uma fase posterior sem necessitar da presença dos pacientes.

The main objective of this thesis is to study photogrammetry as a technique, and compare it to the laser scanning. A theoretical study of the two techniques as well as a practical study of photogrammetry was carried out. After these studies were carried out in order to check how they all worked, it was time to make some experiments with photogrammetry, and to take several groups of photos, with diverse setups and definitions. The objects used were a cube and a sacrum. With those photos and the help of a programme (Autodesk ReMake), models of the objects in the photos were extracted with photogrammetry algorithms. For the conclusions, a reference model was obtained by means of a laser scanner, and all the other models were adjusted spatially to it, using a best fit method by getting hold of a programme (Geomagic) to allow the comparison between the models. The best result had a standard deviation of 0.289 mm. The main conclusion was that the models obtained by using photogrammetry maintain the proportions but do not maintain the scale 1:1 in relation to the real model. In theory, photogrammetry has potential for biomedical application, because it is a passive method and its data acquisition time can be close to zero, and the post processing can…

▼ Like many fields in earth sciences, petroleum geology is an area that requires high-quality spatial data. Recent advances in terrestrial light detection and ranging (LIDAR) technology and photogrammetry resulted in rapid expansion of capabilities in terms of accurate data collection, visualization and analysis, fueled by the need to resolve geometrical properties of smaller scale geologic features that affect fluid flow, such as shale drapes or fractures. The study of sedimentary rock outcrops are of particular interest as they can be used as analogs for similar petroleum reservoir rocks. By harnessing recent developments in 3D digital imaging, this study addresses: (1) characterization of shales and their impact on permeability anisotropy (kv/kh ) in tidally-influenced fluvial deposits; (2) characterization of fracture attributes from 3D surface reconstructions; and (3) the utility of calibrated LIDAR intensity as a remote spectral sensor. The Cretaceous Ferron Sandstone is an outcrop analog for fluvial–tidal systems with primary reservoirs being tidally-influenced point bars. Detailed shale characteristics were measured to test the hypothetical relationships between depositional environment and shale character and to use these observations to make geologically-based estimates of kv/kh . The unique character of each depositional unit was reflected in the estimated kv/kh distributions. More tidally-influenced reservoirs resulted in low kv/kh estimates (0.09), whereas kv/kh for reservoirs that contained predominantly fluvial facies was higher (0.17). Ability of LIDAR as a spectral sensor to detect grain size was tested with two experiments consisting of sandpapers and outcrop application. LIDAR intensity approximated target reflectance after being calibrated. Fine-grained sandpapers and rocks were more reflective of the near-infrared wavelength of the LIDAR laser source. The close agreement between LIDAR-generated and laboratory measured reflectance data signaled the potential of calibrated laser as a spectral tool for effective grain size determination. The fracture system developed within the exposures of Mississippian Boone Formation was characterized using a hybrid approach, combining LIDAR-based digital outcrop models and georeferenced high-quality photomosaics. The results suggest that LIDAR, coupled with referenced gigapixel photomosaics provides an effective medium for fracture identification with the capacity of resolving fracture characteristics with sufficient fidelity, making it an attractive alternative for fracture modeling workflows.

▼ Acquisition of hyperspectral imagery (HSI) from cameras mounted on terrestrial platforms is a relatively recent development that enables spectral analysis of dominantly vertical structures such as geologic outcrops. Although solar shadowing is prevalent in terrestrial HSI due to the vertical scene geometry, automated shadow detection and restoration algorithms have not yet been applied to this technique. This dissertation investigates the fusion of terrestrial laser scanning (TLS) spatial information with terrestrial HSI for geometric shadow detection on a vertical outcrop and examines the contribution of radiometrically calibrated TLS intensity, which is resistant to the influence of solar shadowing, to HSI shadow restoration. The proposed method for shadow detection in the terrestrial HSI leverages an accurately georeferenced, high density point cloud acquired with a TLS sensor to geometrically solve for the presence of shadows in the fused HSI. In contrast to traditional methods applied to airborne imagery, the analysis requires a fully 3D mesh representation of the outcrop rather than a 2.5D surface model. The inclusion of radiometrically calibrated TLS intensity in several existing image shadow restoration techniques is examined, and a direct combination of the active TLS and passive HSI radiometric products proposed and evaluated. Qualitative assessment of the shadow detection results indicates pixel level accuracy, which is indirectly validated by shadow restoration improvements when sub-pixel shadow detection is used in lieu of single pixel detection. The inclusion of TLS intensity in existing shadow restoration algorithms was found to have a marginal positive influence on restoring shadow spectrum shape, while the proposed combination of TLS intensity with passive HSI spectra boosts restored shadow spectrum magnitude precision by up to 40%, and band correlation with respect to a truth image by up to 45% compared to existing methods. The findings demonstrate that sub-pixel shadow detection in terrestrial HSI can be achieved with geometric methods using standard TLS and HSI field collection practices, and the inclusion of TLS intensity can improve restored HSI spectral characteristics. Simulations incorporating multiple laser wavelengths suggest more robust and computationally efficient methods of combining active and passive spectral data for restoring shadow pixel spectra are possible.

▼ The deficiencies of traditional dendrometry mean improvements in methods of tree mensuration are necessary in order to obtain accurate tree metrics for applications such as resource appraisal, and biophysical and ecological modelling. This thesis tests the potential of SfM-MVS (Structure-fromMotion with Multi-View Stereo-photogrammetry) using the software package PhotoScan Professional, for accurately determining linear (2D) and volumetric (3D) tree metrics. SfM is a remote sensing technique, in which the 3D position of objects is calculated from a series of photographs, resulting in a 3D point cloud model. Unlike other photogrammetric techniques, SfM requires no control points or camera calibration. The MVS component of model reconstruction generates a mesh surface based on the structure of the SfM point cloud. The study was divided into two research components, for which two different groups of study trees were used: 1) 30 small, potted ‘nursery’ trees (mean height 2.98 m), for which exact measurements could be made and field settings could be modified, and; 2) 35 mature ‘landscape’ trees (mean height 8.6 m) located in parks and reserves in urban areas around the South Island, New Zealand, for which field settings could not be modified. The first component of research tested the ability of SfM-MVS to reconstruct spatially-accurate 3D models from which 2D (height, crown spread, crown depth, stem diameter) and 3D (volume) tree metrics could be estimated. Each of the 30 nursery trees was photographed and measured with traditional dendrometry to obtain ground truth values with which to evaluate against SfM-MVS estimates. The trees were destructively sampled by way of xylometry, in order to obtain true volume values. The RMSE for SfM-MVS estimates of linear tree metrics ranged between 2.6% and 20.7%, and between 12.3% and 47.5% for volumetric tree metrics. Tree stems were reconstructed very well though slender stems and branches were reconstructed poorly. The second component of research tested the ability of SfM-MVS to reconstruct spatially-accurate 3D models from which height and DBH could be estimated. Each of the 35 landscape trees, which varied in height and species, were photographed, and ground truth values were obtained to evaluate against SfM-MVS estimates. As well as this, each photoset was thinned to find the minimum number of images required to achieve total image alignment in PhotoScan and produce an SfM point cloud (minimum photoset), from which 2D metrics could be estimated. The height and DBH were estimated by SfM-MVS from the complete photosets with RMSE of 6.2% and 5.6% respectively. The height and DBH were estimated from the minimum photosets with RMSE of 9.3% and 7.4% respectively. The minimum number of images required to achieve total alignment was between 20 and 50. There does not appear to be a correlation between the minimum number of images required for alignment and the error in the estimates of height or DBH (R2 =0.001 and 0.09 respectively). Tree height does not appear to affect…

Laser scanning technology has been greatly evolved in the past couple of decades. The advancements made in the development of terrestrial and/or mobile terrestrial laser scanning systems have opened new doors towards building built or non-built scenes and maps. Due to this rapid development, wide variety of applications and methodologies based on this technology have emerged. However, the use of laser scanning directly for scene reconstruction is limited by the orientation, which requires multiple scans of a static scene and the orientation is obtained by matching at least 3 points. This process is cumbersome and time consuming and the sensor should remain static for the whole scan. This issue can be resolved by combing the laser scanning technology with other sensors. Based on this concept, in this thesis, we demonstrate geographic scene reconstruction by integrating laser scanning technology with GPS, IMU and UAV.For this work, we prototype a state-of-the-art aerial mobile scanning system that includes an octocopter fixed with a Hokuyo 2D laser range finder for obtaining the range / depth information, a Phidgets IMU to attain orientation and a Garmin GPS to gather global positional information. In order to maintain a synchronous device operation, all these components were attached to the single board computer using which, different ROS nodes were programmed for each device and were executed in parallel to acquire the data. As the operational frequency of each device varies from one other, an automatic data processing module has been implemented. A wireless communication model has been developed for data transmission from the computer on board to the processing module running on a remote computer. Besides, as each and every device acquires the data in their local coordinate system, a calibration has been performed initially to obtain the global transformation matrix. Next, the reconstruction process was performed offline using 3D tool kit, a multipurpose tool to reconstruct the processed data.The entire work was assessed by evaluating the operational ability of individual components. Various experiments were conducted on both indoor and outdoor scenes. Indoor scenes demonstrate the performance of the developed system whereas outdoor experiments illustrate the ability of the aerial mobile scanning system in partial reconstruction of a geographic scene. However, the flexibility and reconstruction ability of the developed system can be increased either by replacing the used 2D scanner with its 3D version or by using 3 different 2D scanners, one for each cartesian coordinate system.

▼ Biofilms of Actinobacillus succinogenes, grown in a biofilm reactor system, were investigated for structure and cell viability, through microscopic visualisation with a confocal scanning laser microscope (CSLM) and a scanning electron microscope (SEM). Biofilms were sampled and visualised at steady state conditions with the broth containing succinic acid titres between 15 and 21 g/L. All sampled biofilm was 6 days old. Six-day-old biofilms of A. succinogenes showed a heterogeneous biofilm architecture composed of cell micro-colony pillars which varied considerably in thickness, area and shape. Microcolony pillars consisted of a densely packed entanglement of sessile cells. Quantitative analysis revealed that the pillars were mostly large, with a mean pillar diameter of 170 m and a mean thickness of 92 m, although pillar diameter and thickness were variable as they ranged from 25 – 500 m and 30 – 300 m, respectively. In the regions close to the substratum surface, pillars were characterised by having defined borders with a network of channels ranging from 40 – 200 m in width separating them. However, towards the middle of the biofilm depth some of the pillars coalesced. For this reason low cross sectional area coverage of biofilm consistently occurred at the bottom portion of the biofilm whilst the highest coverage was in the middle portion of the biofilm. Regarding cell morphology, very large differences were observed. Planktonic cells were rod-shaped, whereas sessile cells expressed an elongated rod morphology and thus were much longer and thinner compared with planktonic cells. Planktonic cells were 1 – 2 m thick and 4 – 5 m long, while sessile cells were 0.5 – 1 m thick and 5 – 100 m long. Long sessile cells resulted in extensive tangling in microcolony pillars, which may have contributed to the structural stability of the pillars. Fibre-like connections of constant diameter were observed between cells, and between the cells and surface. The diameter of these connections was approximately 20 – 30 nm. Viability stains showed that in the bottom portion (from 0 - 20 m above the substratum surface) of the biofilm, most of the cells were dead. However, the portion of covered area attributed to living cells increased past the middle of the biofilm towards the top part of the biofilm. A high percentage of living cells was thus found towards the top part of the biofilm. Overall, 65% (with 2% standard deviation) of the entire biofilm was composed of dead cells. In this way, the results show that operation at high acid conditions comes at a cost of low overall biomass productivity due to decreased active biomass.

▼ [ES] Esta tesis aborda el desarrollo de métodos de procesado y análisis de datos ALSFW para la caracterización de la estructura vertical del bosque y, en particular, del sotobosque. Para responder a este objetivo general, se establecieron seis objetivos específicos: En primer lugar, se analiza la influencia de la densidad de pulso, de los parámetros de voxelización (tamaño de vóxel y valor de asignación) y de los métodos de regresión sobre los valores de las métricas ALSFW y sobre la estimación de atributos de estructura del bosque. Para ello, se redujo aleatoriamente la densidad de pulsos y se modificaron los parámetros de voxelización, obteniendo los valores de las métricas ALSFW para las diferentes combinaciones de parámetros. Estas mismas métricas ALSFW se emplearon para la estimación de atributos de la estructura del bosque mediante diferentes métodos de regresión. En segundo lugar, se integran métodos de procesado y análisis de datos ALSFW en una nueva herramienta llamada WoLFeX (Waveform Lidar for Forestry eXtraction) que incluye los procesos de recorte, corrección radiométrica relativa, voxelización y extracción de métricas a partir de los datos ALSFW, así como nuevas métricas descriptoras del sotobosque. En tercer lugar, se evalúa la influencia del ángulo de escaneo utilizado en la adquisición de datos ALS y la corrección radiométrica en la extracción de métricas ALSFW y en la estimación de atributos de combustibilidad forestal. Para ello, se extrajeron métricas ALSFW con y sin corrección radiométrica relativa y empleando diferentes ángulos de escaneo. En cuarto lugar, se caracteriza la oclusión de la señal a lo largo de la estructura vertical del bosque empleando y comparando tres tipos diferentes de láser escáner (ALSFW, ALSD y láser escáner terrestre: TLS, por sus siglas en inglés), determinando así sus limitaciones en la detección de material vegetativo en dos ecosistemas forestales diferenciados: el boreal y el mediterráneo. Para cuantificar la oclusión de la señal a lo largo de la estructura vertical del bosque se propone un nuevo parámetro, la tasa de reducción del pulso, basada en el porcentaje de haces láser bloqueados antes de alcanzar una posición dada. En quinto lugar, se evalúa la forma en que se detectan y determinan las clases de densidad de sotobosque mediante los diferentes tipos de ALS. Se compararon los perfiles de distribución vertical en los estratos inferiores descritos por el ALSFW y el ALSD con respecto a los descritos por el TLS, utilizando este último como referencia. Asimismo, se determinaron las clases de densidad de sotobosque aplicando la curva Lorenz y el índice Gini a partir de los perfiles de distribución vertical descritos por ALSFW y ALSD. Finalmente, se aplican y evalúan las nuevas métricas ALSFW basadas en la voxelización, utilizando como referencia los atributos extraídos a partir del TLS, para estimar la altura, la cobertura y el volumen del sotobosque en un ecosistema mediterráneo.

As regiões de cultivo de eucalipto apresentam um grande número de variações ambientais em nível microrregional, como pode ser facilmente constatado quando se observam as diferenças expressivas entre as produtividades florestais de cada área. No entanto, para se avaliar um ambiente, é necessário identificar segmentos específicos dentro de uma paisagem, tratando-se de uma propriedade florestal e, dentro desse estudo, buscar a compreensão das interações que aí se processam. Este trabalho contribui para entender o efeito da face de exposição solar no crescimento de plantios comerciais de Eucalyptus. A proposta metodológica apresentada leva em consideração o conhecimento do meio físico - tendo como base a fisiografia para distinção das faces de exposição solar- além disso, a interação dos fatores fisiográficos com os fatores biológicos são discutidos para subsidiar a tomada de decisão. A acentuada interação genótipo x ambiente presente em muitas culturas faz com que estudos de adaptabilidade a ambientes específicos sejam parte integrante dos programas de pesquisa florestal. A resposta diferenciada dos genótipos a ambientes favoráveis e desfavoráveis pode auxiliar o gestor florestal na alocação assertiva dos materiais genéticos para maximizar a produtividade. O escaneamento a laser aerotransportado, ferramenta de uso precoce no Brasil, é um sensor óptico ativo que mede a distância até os objetos-alvo e foi utilizado para a obtenção da altura das árvores. A área de estudo está localizada na região sudoeste do estado de São Paulo. Dentre as métricas disponíveis do processamento utilizou o percentil 90 de altura para estimar a altura de plantios comerciais homogêneos de Eucalyptus. Elaborou-se a análise de variância considerando um delineamento fatorial contemplando a face de exposição solar (norte e sul) e o material genético (clones comerciais), além da interação entre ambos para observar o efeito da face no crescimento em altura do povoamento. Para florestas abaixo de quatro anos de idade observou-se que os plantios de face sul cresceram menos que os da face norte. Para florestas acima de 5 anos essa diferença entre face continua, contudo, quando concluído o desdobramento da interação fatorial observou-se que os materiais genéticos plantados em face norte não diferem entre si, mas a diferença se mantém para florestas em face sul.

The eucalyptus cultivation regions boast a large number of environmental variables in micro-regional level, as can easily be seen when studying the expressive differences between the productivity of each forest area. To evaluate an environment, however, it is necessary to identify specific segments within a landscape with regards to a forest property and within that landscape study to seek the understanding of the interactions that takes place in the process. This work contributes to a better understanding of the effect of the aspect on growth in commercial plantations of Eucalyptus. The methodological approach presented in this work takes into account the knowledge of the physical environment,…

A silvicultura urbana é um dos elementos essenciais à manutenção da qualidade de vida nos grandes centros urbanos. A existência de uma ampla rede de arvores distribuída ao longo das vias e dos espaços públicos atua promovendo a qualidade do ar, a conservação de água, o conforto térmico, acústico e psicológico dos cidadãos. Florestas urbanas são capazes de amenizar as emissões dos Gases do Efeito Estufa (GEE), tais como o CO2, atuando como sumidouros. Visto sua importância, novas aplicações de ferramentas de sensoriamento remoto têm surgido para auxiliar no planejamento e implantação da silvicultura urbana. O sistema de escaneamento a laser aerotransportado LiDAR (Light Detection And Ranging em inglês), gera uma representação em três dimensões do objeto alvo por meio de uma nuvem de pontos georreferenciados. O cruzamento com sensores de altíssima resolução espectral proporciona analises mais aprofundadas do objeto, podendo-se extrair diversas métricas florestais tais como altura, área basal, e até mesmo espécie. O trabalho teve como objetivo verificar a contribuição do uso de informações derivadas da nuvem de pontos LiDAR, na identificação e classificação das seis espécies florestais mais frequentes do Parque Municipal Américo Renné Giannetti em Belo Horizonte, Minas Gerais, Brasil, a fim de auxiliar no planejamento e manejo da silvicultura urbana. Para tanto, por meio de classificação supervisionada, cruzou-se informações de levantamento de campo, segmentação de copas, pontos de topo de copa de árvore extraídos da nuvem LiDAR, e uma imagem multiespectral WordlView-2. A acurácia da classificação foi medida por análise da exatidão global do processo e por meio do índice Kappa. Os pontos de topo de copa de árvore derivados da nuvem LiDAR contribuíram para a localização e classificação das classes referentes às espécies florestais, quando comparados ao mesmo processo sem estes pontos. A segmentação das copas executada pelo programa eCognition facilitou o lançamento das amostras treinamento e teste. O classificador ECHO conseguiu melhores valores de acurácia e índice Kappa, frente aos outros classificadores do programa Multispec. O uso de informações provenientes da nuvem de pontos LiDAR se mostrou promissor em imagens multiespectrais de ambiente florestal urbano, aumentando a acurácia geral da classificação supervisionada.

Urban forestry is a key element to maintaining the quality of life in urban centers. The existence of a broad network of trees distributed along roads and public spaces acts to promote air quality, water conservation, thermal comfort, acoustic and psychological citizens. Urban forests are able to mitigate the emissions of Greenhouse Gases (GHG) such as CO2, acting as sinks. Since its importance, new applications of remote sensing tools have emerged to assist in planning and implementation of urban forestry. The laser scanning system airborne LiDAR (Light Detection And Ranging), generates a three-dimensional representation of the target object through a cloud of points georeferenced. The crossing…

▼ In 2012, the Abyss Twisted-pair Imaging System (ATIS) was built by the National Yat-sen University for gas hydrate investigation off southwest Taiwan. After several deep-towed operations, we found that the battery life of the ATIS is a bit short for its video storage and recording capacity. In addition, we found that, on the ATIS, the capabilities of adding optional sensors, sizing objects, obstacle avoidance, and heading adjustment are absent. Therefore, in this study, a new vehicle ATIS II was developed to extend battery life and to allow for providing the capabilities of adding optional sensors, sizing objects, obstacle avoidance, and heading adjustment. On the issue of increasing battery life, the ATIS was originally equipped with the lithium ion batteries which can provide power for as long as 2.5 hours. Considering the cost of the battery, the ATIS II adopted the Absorbent Glass Mat (AGM) batteries as the power source. By the use of the AGM batteries, the ATIS II can sustain the operation for 5 hours that is the average recording storage time for the ATIS video system. For adding optional sensors on the ATIS II, a junction box was designed to provide a simple, compact and low cost solution to the problem of accessing optional sensor data inputs. For object scaling, a parallel laser system was incorporated into the imaging system of the ATIS II. Two parallel lasers separated by a known distance (30 cm) are projected onto the seafloor object. When a video is taken, the laser projections on the target provide a scale bar that can be used to measure the size of objects in the image. As for obstacle avoidance, it is extremely important to always know whether there is obstacle in the way or not while towing an underwater vehicle. Therefore, a scanning sonar was integrated into the ATIS II for detecting the obstacle during the tows. Considering the issue of heading adjustment, a fixed fin was mounted on the ATIS for stabilizing the vehicle in yaw motion while towing the ATIS. However, the heading of the ATIS can be difficult to maintain on the course direction when environmental forces act on the vehicle in an unpredictable manner. When the vehicle heading deviates from the course direction, heading adjustment is needed for better quality of seafloor video observation. Therefore, an adjustable fin was designed for the ATIS II so that the fin angle can be altered to maintain the vehicleâs heading on the towing direction. Based on the improvement designs mentioned above, the water proof housings for batteries and electronics are redesigned. As well, a new frame for ATIS II are designed for optimum placement of electronic housings, junction box, the imaging system, sensors, and the adjustable fin.

▼ The purpose of this paper is to design a laser scanning system for a high temperature and acidic environment to measure small-scale surface roughness of seabed and to collect information related to calcium carbonate debris. The study comprises two parts. One is to construct the hardware and software of the laser scanning system. Two is to test the system at sea. The system were tested at Kuishantao sea area, an area with many submarine springs. The temperature of the hot water from the submarine springs can be as high as 126Â°C. Key substances from this type of hot springs are surfur and air bubbles composed of CO2, N2, O2, SO2, and H2S. These chemicals make the sea water in this area acidic, and the pH value can be less than 2. In other words, this sea area is a high temperature and very acidic environment According the acidic resistant test result, the researchers decided to use Polypropylene (PP) as the material. The laser scanning system captures information automatically, and it uses industrial single board computer (PC104) as the control platform. The researchers selected red laser, which is monotonous, directional, and coherent Lithium batteries, can be recharged repetitively, were used to supply the power. High-precision positioning, high resolution, and with easy speed and angle control stepping motors were chosen for the system. For the software, the researchers chose the Window operating system. The hardware and software of this system are highly compatible. Operating the system is very intuitive because windows are used as the interface, and the hardware has high supporting capacity. This arrangement makes data analysis later on very convenient. Images acquired from conducting the actual experiment at sea that need to be processed. A CCD camcorder with fixed location and angle was used to capture images. With the high brightness characteristic of laser and simple threshold values for screening, the researchers got the pixel position of laser beans. Then a calibrated the camcorder was used to switch the pixel coordinates to obtain the actual size of the object.

▼ Forests are an important part of the natural ecosystem, providing resources such as timber and fuel, performing services such as energy exchange and carbon storage, and presenting risks, such as fire damage and invasive species impacts. Improved characterization of forest structural attributes is desirable, as it could improve our understanding and management of these natural resources. However, the traditional, systematic collection of forest information – dubbed “forest inventory” – is time-consuming, expensive, and coarse when compared to novel 3-D measurement technologies. Remote sensing estimates, on the other hand, provide synoptic coverage, but often fail to capture the fine- scale structural variation of the forest environment. Terrestrial laser scanning (TLS) has demonstrated a potential to address these limitations, but its operational use has remained limited due to unsatisfactory performance characteristics vs. budgetary constraints of many end-users. To address this gap, my dissertation advanced affordable mobile laser scanning capabilities for operational forest structure assessment. We developed geometric reconstruction of forest structure from rapid-scan, low-resolution point cloud data, providing for automatic extraction of standard forest inventory metrics. To augment these results over larger areas, we designed a view-invariant feature descriptor to enable marker-free registration of TLS data pairs, without knowledge of the initial sensor pose. Finally, a graph-theory framework was integrated to perform multi-view registration between a network of disconnected scans, which provided improved assessment of forest inventory variables. This work addresses a major limitation related to the inability of TLS to assess forest structure at an operational scale, and may facilitate improved understanding of the phenomenology of airborne sensing systems, by providing fine-scale reference data with which to interpret the active or passive electromagnetic radiation interactions with forest structure. Outputs are being utilized to provide antecedent science data for NASA’s HyspIRI mission and to support the National Ecological Observatory Network’s (NEON) long-term environmental monitoring initiatives.

▼ Targeted adaptive physiological trait introgression, a method by which breeders seek to introduce specific characteristics into breeding germplasm in a specific and targeted manner, is one of the primary methods breeders are using to develop cultivars optimized for performance and yield under heat and drought conditions. In traditional breeding platforms, this is carried out in a stepwise fashion, with the crossing of parental lines and the phenotype-driven selection of offspring. As with other adaptive physiological traits, rapid field-based high-throughput phenotyping of early season aboveground biomass and ideal root architecture is limited by our inability to accurately and nondestructively characterize these important traits. Terrestrial laser scanning (TLS) and ground penetrating radar (GPR) have the potential to fill this gap by non-invasively estimating biomass and mapping three-dimensional above- and below-ground vegetation. The research objective was to evaluate the use of TLS to estimate aboveground wheat (Triticum aestivum L.) biomass. Linear regressions comparing mean canopy height and total plot forage yield for each experimental plot across four replications was poorly correlated (R² 0.08). Mean plot normalized difference vegetation index measurements were evaluated against total plot forage biomass with limited correlation (R² 0.036). The mean value of the TLS elevation points had the highest correlation with both plot (R²⁰.09458) and sub plot (R² 0.37984) forage yield as compared to traditional platforms. GPR is a remote sensing technology that has been successfully used in the evaluation of coarse tree root biomass. Incorporating GPR into current crop phenotyping methodologies could potentially provide a long awaited solution to the current inability to efficiently phenotype roots under realistic field conditions. Here, the utility of using GPR to estimate root biomass of wheat was evaluated. GPR ability to predict root presence and absence was tested and GPR was able to differentiate root mass from soil significantly (α = 0.95, t = 1.96022). Linear regression between Log10 of the mean GPR amplitude return at the 0-3 ns range was compared with agronomic breeding traits. Overall increased amplitude was observed in plots scoring higher with regard to overall yield and yield components.
