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 Dakota Sandstone in western Sarpy County. This dataset was developed as part of a cooperative study between the Papillion-Missouri River Natural Resources District (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 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 (Geoscene 3D) that would allow PMRNRD [...]

In 2016, the 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 (Geoscene 3D) 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 PMRNRD 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.

Purpose
These datasets were created for input into a 3-D visualization program which combines airborne electromagnetic geophysical data along with supporting information for visualization and geological modeling. Contour files were created to provide the associated files in a format that could be easily viewed with geospatial information system (GIS) software.
