The goal of this project is to provide land cover of the Chesapeake Bay area for use in modeling run-off into the Chesapeake Bay. The Layer (.lyr) files are ESRI files that are associated with their corresponding Image (.img) files under Arc Map that had the color map (.clr) file applied to their symbology to provide an initial set of consistent colors for display of all Land Cover Maps in the CBLCD 2011 Edition Data Release.
