Baseline Coastal Survey & Classification Product Derived From CASI Data

Alabama Coastline Hyperspectral Survey & Land Cover Classification 6900 line kms of hyperspectral CASI (Compact Airborne Spectrographic Imager) data were collected for the U.S. Army Corps of Engineers (USACE), Mobile District to establish a comprehensive GIS for the Mobile River Basin. The study area includes the Alabama Gulf Coast and barrier islands, wetlands surrounding Mobile Bay, and river floodplain. The project was managed by 3001, Inc. Project Statistics at a Glance Number of flight blocks/lines:   19/441 Number of line km/miles:   6900/4287 Total CASI image mosaics/area:   188/2200 km2 % Mosaics analyzed/area:   49%/1071 km2 CASI Project Features 16-bit CASI imagery (VNIR, ~400-1000 nm); 1 m resolution, 36-band sensor confi guration; Radiometrically calibrated imagery, atmospherically corrected to          reflectance units; Geometric calibration performed using photogrammetric bundle adjustment procedure (correcting for sensor alignment offsets); Automated geocorrection mosaicking and orthocorrection using LIDAR DEM. Project Goals and Map Products ID of submerged and fl oating aquatic vegetation; Mapping of major wetland plant species and determination of water clarity; Coastline delineation; and Mapping land cover communities. In support of these goals, a comprehensive ground truth database was delivered along with the processed imagery and derived map products (USGS DOQQ-compatible). The entire project dataset is intended to serve as a baseline from which to measure future changes in the Alabama coastal environment and Mobile Bay estuaries. Interested in a similar project?
