2018 Long Island, NY DMC 4-Band 8 Bit Imagery

This data set consists of a set of aerial triangulated 4-band orthophotos (.tif format) with a .5 meter resolution of the Long Island South Shore that includes the areas of Great South Bay, Moriches Bay, and Shinnecock Bay. The imagery was flown over three days, May 9, 11 and 24, 2018. The digital imagery was acquired by Richard Crouse & Associates(RCA) using an Intergraph DMC2e 230-23522 digital mapping camera. The resulting photographic images were aerotriangulated by Leading Edge Geomatics and reviewed for quality by Dewberry. The imagery was collected under environmental conditions favorable to mapping shallow submerged habitats, in particular seagrass. Missions were timed to coincide with low tide, sun angles below 30 degrees, calm sea state, and low-turbidity. The missions were also scheduled to take advantage of adequate seagrass biomass and minimal brown tide events. Close coordination with local observers on the ground was maintained to ensure good water clarity during data acquisition.
