• Physiography of the Des Moines Lobe

    This 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. Includes a 10 m resolution grid interpreting the surficial geology from gSSURGO. Also includes a polygon shapefile that delineates the Des Moines Lobe into physiographic regions based on that surficial geology map and relief.

  • Using Soil Surveys to Delineate Quaternary Parent Materials and Landforms (2010 Binghamton Geomorphology Symposium)

    We sought to create the best possible Quaternary geology map of the Des Moines Lobe solely using readily available National Cooperative Soil Survey (NCSS) data. We then sought to test whether that map is comparable to Quaternary geology maps previously published by geologists. Categorization of soil map units with respect to geologic unit successfully created a detailed Quaternary geologic map for the Des Moines Lobe, showing strong agreement with the existing Quaternary geologic maps while adding a user-controlled level of scale.

  • Using soil surveys to map Quaternary parent materials and landforms

    The integration of soil survey maps with Geographic Information Systems (GIS) allows for an almost infinite level of collaboration across disciplines that use information related to soil databases. This study created a Quaternary geologic map by categorizing soil descriptions into a geologic context and joining the attributes with the Soil Survey Geographic (SSURGO) database in ArcGIS®. The resulting map communicates many of the spatial intricacies of the Des Moines Lobe landform with 15 map units based on geologic units.
