ABSTRACT: This Study uses Landsat 8 satellite imagery to perform salt marsh mapping analysis to reveal the spatial distribution and conditions of salt marshes along the north-mid- Atlantic coast. The results would provide the baseline data (2017) for change analysis and comparison for similar data in other years. NOAA Coastal Change Analysis Program (C-CAP) 2010 data were used as the reference to delineate the salt marsh and adjacent areas from Landsat 8 imageries. There were 6 scenes downloaded for the study area ranging from July 7, 2017 to September 11, 2017 with less than 10 percent cloud coverage. This study used an object-based image analysis (OBIA), which first breaks up the image into objects and then classifies the objects based on their spectral signature. Finer spatial resolution salt marsh mapping derived from Worldview-2 and Quickbird-2 satellites for Fire Island National Seashore are used as ground verifications. The objective of this study is to (1) identify the salt marsh extent along the mid-Atlantic coast line; (2) improve classification accuracy of Landsat 8 imagery in salt marsh mapping. Result is to be presented at the conference.
