Combined the local existing data with the LiDAR data of Wallops Island area, Virginia provided by NASA, the high-resolution DSM models were obtained with an automated algorithm. The DSM were furthered classified and processed to produce a number of DTM. The DSM and DTM were used to study the coastal processes. Further analysis of the data was done using piping plover nesting sites and endangered turtle species’ egg-laying locations provided by US Fish and Wild Life Service (USFWS). The results demonstrated that the piping plover uses the leeward side of sand dunes to nest and thus protect their young birds from offshore physical processes like waves, wind, etc. The DTM and marine data were also integrated to study the beach erosion processes and how to protect the coastal area with beach nourishment. This project not only examined the island morphology change over time and but also explored the potential impacts of sea level rise on coastal ecosystem due to climate change.
