Abstract Shoreline mapping is of critical importance for coastal communities. It supports nautical charting, coastal zone management, legal boundary determination, analyzing shoreline erosion and other threats of climate change, and a host of other applications. A tide-coordinated shoreline is representative of the shoreline at certain tidal stage, e.g., Mean Lower-Low Water (MLLW) or Mean High Water (MHW). Since the establishment of the Survey of the Coast in 1807, mapping of tide-coordinated shorelines has been a challenging operation. In the past, analog devices, such as plane tables and telemeter rods, had been used in mapping the tide-coordinated shoreline for nautical chart production. Although shoreline mapping from such techniques provided high-quality shoreline, the procedure requires massive amount of time, manpower and budget. The standard method to map tide-coordinated shorelines was later shifted to aerial photogrammetry in 1927. Advantages of conducting coastal surveys using aerial photogrammetry over the conventional ground survey include enabling surveying of large areas in a short time, while maintaining good accuracy. Today, approaches to tide-coordinated shoreline involve recent advances in technologies and methods, including global positioning system (GPS), light detection and ranging (LIDAR), satellite imagery, and auto-feature extraction from imagery. Additionally, LIDAR has currently begun to be utilized in NOAA’s national shoreline production for MHW shoreline, along with MLLW shoreline from photogrammetric compilation deriving tidally-referenced aerial imagery. This thesis discusses coastal mapping and surveying work focused on approaches to tide-coordinated shoreline. A brief history of shoreline mapping in the United States, dating back to the early era of U.S. coastal survey, is presented as well as current standard procedures of tide-coordinated shoreline mapping, including quality of work and efficiency of the work process. Definitions of a shoreline and some of its variations, usually misinterpreted and misused, are addressed to give a basic understanding. Implementations of modern technologies and methods in derivation of tide-coordinated shoreline will then be reviewed and discussed regarding the accuracy and efficiency of the shoreline products. Finally, trends and developments of tide-coordinated shoreline mapping approaches regarding advancements of technologies in the future are analyzed and discussed in the thesis.
