Looking for agency-wide GIS data? Check here.
Here you will find all of our geologic data for download in the ESRI ArcGIS 10.0 file geodatabase format. Some geodatabases still exist in 9.31 file format, and others have been upgraded to ArcGIS Pro 2.6 format. You will need to have GIS software such as ArcGIS or QGIS to open these geodatabases.
Unfortunately, we cannot offer data in shapefile format at this time. There are several open-source GIS software packages, such as QGIS, that can convert geodatabases into shapefile format. There are many tutorials available online to help you get started with QGIS if you're unfamiliar with the software.
