These items were used to create the pie-chart map in chapter 3 of the Mid-Atlantic Atlas. Purpose: These data were created as part of a regional assessment of landscape conditions in the mid-Atlantic region (SFR 3) (Jones et al., 1997).

Source_Information: Source_Citation: Citation_Information: Other_Citation_Details: Process_Step: Process_Description: A raster dataset in ARC/INFO Grid representing landcover was summarized by each 8-digit hydrologic accounting unit in Federal Region Three. The 15 class landcover dataset was aggregated into the general categories of water, urban, forest, and agriculture. Percent coverage for each huc was determined by dividing the number of pixels in each category by the total number of pixels in the watershed. In ARCPLOT, these percentages were used with the POLYGONSPOT command to create pie charts showing the proportion of each huc in each landcover class.
