Data Name

Description

bufnca5

Arc/Info polygon coverage of NC streams downloaded from 1:2,000,000 scale DLG from USGS.

city

Shape file of urban land use polygons in study area. Created by selecting Land use polygons with LULC code equal to "urban".

component

Info table associated with STATSGO soils coverage. Provides information about the components that make up each STATSGO mapunit.

flood

Shape file of flood prone areas in the study region. Created by converting nc2 polygons with components prone to flooding into a shape file coverage.

flor.e00.gz

flor

Arc/Info polygon coverage created by converting flor.e00.gz into Arc/Info format.

flor2

Arc/Info polygon coverage of flor converted into an albers projection.

flor3

Arc/Info polygon coverage of LULC for study region. Created by clipping the flor2 coverage with the nc coverage.

florinfo

Data file describing attributes of LULC polygons.

layer

Info table associated with STATSGO soils coverage. Provides information about the layers that make up each STATSGO component.

map unit

Info table associated with STATSGO soils coverage. Provides information about each STATSGO polygon known as a mapunit.

medclay
