New Hi-Res Dataset: “Groundbreaking Land Cover Data to Support Chesapeake Bay Restoration Efforts”

From the Chesapeake Bay Program:

The Chesapeake Bay Program today announced the completion of the Chesapeake Bay High Resolution Land Cover Project, a landmark initiative to improve information about the features of the Bay watershed landscape.

The new high-resolution data on land cover—such as buildings, tree canopy and water—will support the Bay Program’s efforts to evaluate progress toward reducing the amount of pollution flowing into the Chesapeake Bay.

Chesapeake Conservancy—an Annapolis, Maryland-based nonprofit—led a partnership with the University of Vermont and Worldview Solutions, Inc. to complete the project, which is one of the largest high resolution land cover datasets in the nation. A team of geospatial analysts worked for ten months to produce one-meter by one-meter resolution land cover data for nearly 100,000 square miles, spanning the entire Chesapeake Bay watershed and surrounding counties. Offering an unprecedented degree of accuracy, the new dataset provides 900 times the amount of information as the existing watershed-wide data

Available to the public at no cost, the high resolution land cover data will aid in the restoration and conservation work of federal, state and local government agencies, nonprofits, academic institutions and other organizations by allowing for better characterization and understanding of the landscape.

New geographic data for thousands of square miles in the Chesapeake Bay watershed will provide 900 times more detail than had been available about the landscape around the ecologically significant estuary.
