<DIV STYLE="text-align:Left;"><DIV><DIV><P STYLE="margin:0 0 0 0;"><SPAN>This layer contains the percentage of generalized land cover by 12-digit hyrdologic unit codes (HUCs). The 2011 NOAA C-CAP land cover raster was converted to a shapefile, generalized to minimize the number of categories, intersected with 12-digit Hydrologic Unit Codes (HUCs), and dissolved by generalized category and 12-digit HUC. Percent calculations were then made based on the total area of each 12-digit HUC.</SPAN></P><P STYLE="margin:0 0 0 0;"><SPAN /></P><P STYLE="margin:0 0 0 0;"><SPAN>Fields: subwatershed name, subwatershed HUC, and percent cover in generalized categories, as follows: "Agricultural" includes pasture and cultivated area; "Forest" and "Wetland" includes all types within those broader categories (e.g. evergreen, decidious, etc); "Other" includes water and barren land; and "Developed" includes all gradations (high density, low density, etc). </SPAN></P><P STYLE="margin:0 0 0 0;"><SPAN>The field "area_sqmi" is the area (in square miles) of the entire 12-digit HUC. </SPAN></P></DIV></DIV></DIV> |
