TCarta Delivers Satellite-Derived Bathymetry to NOAA for U.S. Coastal Mapping Pilot

Validated with ICESat-2 Laser Data
DENVER, Colorado, 3 May 2021 – TCarta Marine, a global provider of marine geospatial products, has supplied the National Oceanic and Atmospheric Administration (NOAA) with satellite-derived bathymetry (SDB) validated by green laser altimeter data from the NASA ICESat-2 satellite for two U.S. shallow-water coastal areas.
2m SDB in Nantucket Sound, MA, produced using WorldView satellite imagery with ICESat-2 tracks overlaid.
TCarta was the subcontractor on the prime contract awarded to Woolpert, an international geospatial firm headquartered in Dayton, Ohio.
The NOAA pilot focused on two shallow-water regions that were 3,000 square kilometers in total area – one in the Green Bay area of western Lake Michigan and the other around Cape Cod and Nantucket Sound. Both areas experience natural forces that alter the underwater terrain faster than traditional bathymetric surveys can be completed.
