WEB-BASED GLACIAL AND BEDROCK GEOLOGIC MAP PRODUCTS AND DATABASES FOR MARION COUNTY, INDIANA
The Marion County Web site links an Internet Map Server (IMS) and database to provide a portal to the IGS’s enterprise geodatabases that allows users to efficiently create, manage, update, and distribute maps and data. The IMS site retrieves maps and cross sections of Marion County completed during earlier IGS mapping projects. Map layers pertaining to bedrock geology, surficial geology, hydrology, infrastructure, and imagery layers are included. Database information includes (1) lithologic information compiled from water-well records stored in the Indiana Department of Natural Resources, Division of Water archives, (2) natural gamma-ray geophysical log data, (3) stratigraphic test hole data, and (4) petroleum well-record data. The development of the Web site is funded by the IGS and the Great Lakes Geologic Mapping Coalition.
