Physiography of the Des Moines Lobe

DML_physiographyThis GIS package contains a pair of spatial data sets that have been generated for the purpose of studying the physiography of the Des Moines Lobe landform region. One is a surficial geology map of the Des Moines Lobe and surrounding areas. This raster was generated from the USDA-NRCS gSSURGO spatial database. The attributes were extracted from the NRCS official soil series descriptions (OSD), but at times some additional interpretation was needed based on typical soil profile properties and spatial relationships with better-defined soil series. The other data set delineates and divides the Des Moines Lobe by physiographic regions. These regions are based on major moraines denoting surfaces of notably different age as well as important changes in surficial geology and topography. Because of the close relationship between these maps and topography, digital elevation models from the USGS would be complementary to these data sets.
