Overview
The U.S. Army Corps of Engineers’ National Coastal Mapping Program provides high-resolution elevation and imagery data along U.S. shorelines on a 5 to 7 year update schedule. The program uses the Compact Hydrographic Airborne Rapid Total Survey (CHARTS) system, which integrates topographic and bathymetric lidar sensors, a digital camera, and a hyperspectral scanner on a single remote sensing platform for use in coastal mapping and charting activities. One derived data set from CHARTS is orthomosaics, which are created by ortho rectifying and mosaicing individual images into mapped "boxes" that extend approximately five kilometers (km) along the shore.
The Corps’ Bottom Reflectance and Bathymetry and Topography data are also available in Digital Coast.
