Vegetation and Biomass in Tidal Marshes

Mississippi River Delta tidal marsh

Map of tidal marsh green vegetation, non-vegetation, and open water at 1m resolution for the Mississippi River Delta site in Terrebonne and St. Mary Parishes, Louisiana.

Three new datasets from NASA's Carbon Monitoring System provide high-resolution maps of six US tidal marshes.

Mapping Surface Waters from ABoVE

Open surface waters for a location in Canada

Orthomosaic imagery taken from a Beechcraft Super King Air B200 aircraft traveling north of the Mackenzie River in the Dehcho Region of Canada.

NASA's 2017 ABoVE airborne campaign provides high-resolution, georeferenced, three-band orthomosaics of digital imagery to validate maps of Arctic surface water extent.
