abstract Land use for long-term Rhode River study watersheds. Used ARC/INFO to trace land use patches from 1984 1:2400 b/w aerial photos. The resulting coverage was geographically referenced using control points from 1:2400 topographic maps. The photos and maps were both obtained from the Anne Arundel Co. Office of Planning and Zoning. Updated the coverage from 1989 b/w 1:2400 photos and 1990 color slides. Verified land use in all patches observable on the ground.
