Summary
This dataset contains digitized land use/land cover (LULC) polygons for years between 1998 and 2013 for six watersheds within and near the Clarksburg Special Protection Area located in Montgomery County, Maryland, USA. Each polygon is representative of the LULC for a specific year within 500-foot buffered watersheds. Watershed boundaries for Cabin Branch (CB), Crystal Rock (CR), Soper Branch (SB), Tributary 104 (T104), and Tributary 109 (T109) were derived using USGS topographic maps while Ten Mile Creek (TMC) was derived using Montgomery County, Maryland LiDAR data. The Habitat Digitizer Extension add-in from NOAA for ArcMap was used to customize a hierarchical classification scheme to attribute polygons delineated by visually interpreting [...]
