Digital Geologic Maps

The digital geologic map data is in shapefile format. These data are published in Environmental Systems Research Institute, Inc. (ESRI, Inc) ArcGIS 9.1 using the Publisher extension to be distributed in ArcReader format. ArcReader must be installed for the data to be viewed. (ArcReader free download page ) The digital map is accompanied by its requisite metadata and by a map explanation presented in Adobe Acrobat PDF format. The explanation is similar to that presented in the explanatory sheet of the printed geologic map; the primary difference is that no detailed geologic unit descriptions are presented here. For detailed rock descriptions, stratigraphic diagrams, structural cross sections, and source bibliography, the user is referred to the original printed map (Szabo and others, 1988).

 

The Geological Survey of Alabama (GSA) participates in the STATEMAP component of the National Cooperative Geologic Mapping Program. STATEMAP is a competitive federal grant program requiring matching state funds and is coordinated and managed by the U.S. Geological Survey. The purpose of the program is to produce new, detailed geologic maps of areas deemed critical to the state. In Alabama, STATEMAP geologic mapping has focused on areas where rapid urban and industrial growth is occurring. Through STATEMAP, GSA has completed and published more than 30 new geologic maps at the 7.5-minute (1:24,000) scale, and several more are in progress. The published maps are color plots and are accompanied by explanations and booklets summarizing the geology of the quadrangles. The maps and supporting documents are available for purchase from the Publications Sales Office. Digital files for selected quadrangles are available below. Digital files for additional quadrangles will be posted as they become available. below.
