This is an indication of erosion potential and surface runoff. 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: This Grid was created using a CON statement in ARC/INFO. Landcover classes 5 and 6 from the MRLC landcover data were used to represent croplands, and slopes greater than 3% were selected from the maia_slope dataset. The resulting grid shows all areas where crops lie on slopes greater than 3%.
