The above image was clipped from ArcView. It shows BASINS soil-type data (pink layer)
overlaid on the shapefile elevation data (blue layer).
As part of the BASINS "core" data, soil type and the necessary HYGRP (hydrologic soil group) field are included as shape and .dbf files, respectively. This data set provides a soil association map in ArcView shapefile format for the conterminous United States. The shapefiles have been prepared and distributed by EPA regions. This data is a subset of the original STATSGO data developed by the National Cooperative Soil Survey. As a necessary part of a rainfall/runoff model, the soil data from the EPA is a quick and useful alternative to NRCS STATSGO data that require some formatting before their implementation into a model.
