Monitoring Changes in the Chesapeake Bay Watershed
on January 31, 2013
Landsat is a critical and invaluable tool for characterizing the landscape and mapping it over time. Landsat data provides a baseline of observations for science about how human activities on the land affect water quality, affect wildlife habitat, affect air quality. The satellite imagery covers the entire 64,000 square miles of the Chesapeake Bay watershed (spanning six states and the District of Columbia). Without it we wouldn't be able to really understand how sources of nutrients and sediment have changed and where they are in the Chesapeake Bay.
The Landsat Program is a series of Earth-observing satellite missions jointly managed by NASA and the U.S. Geological Survey.
Landsat imagery is critical for monitoring changes in developed area, tree canopy, farm fields, and all the landscapes that make up the 64,000 square miles of the Chesapeake Bay watershed, spanning six states and the District of Columbia.
