The Delaware Geological Survey has released the Delaware Geologic Information Resource (DGIR), an online data display tool and map viewer for geologic and hydrologic information, as a "beta" site. DGIR was designed to deliver the most commonly available and requested geologic and hydrologic information that is appropriate for use in hydrologic studies, required by regulation and ordinance, and to support state resource management decisions.
Numerous DGS-produced datasets are included in DGIR, such as surficial and bedrock geologic maps, water table and aquifer grids, well locations, hydrographs, geophysical and lithologic logs, and more. Many non-DGS dataseta are also included for reference purposes, such as wetlands, streams and larger water bodies, well-head protection areas, watersheds, digital elevation model, and others.
The intended audience for DGIR is the Delaware professional community. This includes not only Piedmont and Coastal Plain geologists and academic researchers, but also hydrologists, engineers, and state and local officials who need raw data and interpretive information on Delawareâs water resources for planning or permitting purposes, and many others who have a strong need for geoscience information.
DGIR was initially created under a grant from Delaware Department of Natural Resources and Environmental Control (DNREC), Water Supply Section.
