Name: EgleSde.EGLESDEADMIN.LandCoverSummaryInformationByHUC12

Display Field: HUC12Name

Type: Feature Layer

Geometry Type: esriGeometryPolygon

Description:

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.

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).

The field "area_sqmi" is the area (in square miles) of the entire 12-digit HUC.
