Cherry, M.L., Schaepe, N.J., and Flynn, A.S., 2023, Datasets of altitude of the top of the Dakota Sandstone, top of the Pennsylvanian-age units, and water-level in western Sarpy County, Nebraska: U.S. Geological Survey data release, https://doi.org/10.5066/P9Z7PW1K.
Summary
This dataset includes a grid raster and contour line file representing the estimated altitude of the top of the Pennsylvanian-age units in western Sarpy County, Nebraska. This dataset was developed as part of a cooperative study between the PMRNRD and USGS which began in 2017. The goal of this study was to develop a hydrogeologic visualization model of western Sarpy County using GeoScene3D. In 2016, the Papillion-Missouri River Natural Resources District (PMRNRD) contracted airborne electromagnetic surveys (AEM) of the area to be completed to better understand the stratigraphy and hydrogeology of the western Sarpy County area. The PMRNRD determined that they wanted to incorporate the AEM data into a visualization tool (Geoscene3D) [...]
Summary
This dataset includes a grid raster and contour line file representing the estimated altitude of the top of the Pennsylvanian-age units in western Sarpy County, Nebraska. This dataset was developed as part of a cooperative study between the PMRNRD and USGS which began in 2017. The goal of this study was to develop a hydrogeologic visualization model of western Sarpy County using GeoScene3D. In 2016, the Papillion-Missouri River Natural Resources District (PMRNRD) contracted airborne electromagnetic surveys (AEM) of the area to be completed to better understand the stratigraphy and hydrogeology of the western Sarpy County area. The PMRNRD determined that they wanted to incorporate the AEM data into a visualization tool (Geoscene3D) that would allow PMRNRD staff to easily interact with the AEM data and integrate it with other hydrogeologic and groundwater-quality data. The completed Geoscene3D project was assembled to allow Papio-Missouri River Natural Resources District managers to visualize the groundwater systems and associated water-quality results in Sarpy County and enable them to make more informed groundwater resource-planning decisions in the future.
The raster file was created for use within the Geoscene 3D program which combines airborne electromagnetic geophysical data along with supporting information for visualization and hydrogeological modeling. A contour shapefile was created from this raster to provide estimated altitude for the top of the Pennsylvanian-age units in western Sarpy County that could be easily viewed with geospatial information system (GIS) software.
