Looking for agency-wide GIS data? Check here.
Here you will find geologic data in Geographic Information Systems (GIS) and other formats. Most of the data provided here are in the ESRI ArcGIS 10.0 file geodatabase format. Some still exist in 9.31 file format, and others have been upgraded to ArcGIS Pro 2.6 format. Unfortunately, we cannot offer data in shapefile format at this time. There are several open-source GIS software packages that can convert geodatabases into shapefile format.
