Maps
Maps are an important component of the DGS information dissemination effort. DGS map products put the results of our geologic and hydrologic investigations in a geospatial format. High-quality individual map products are available at a variety of scales on a range of geologic and hydrologic topics in paper format and, for more recent maps, in digital image and GIS-compatible formats. DGS maps are also increasingly available via our interactive internet map service, the Delaware Geologic Information Resource (DGIR).
