Web-based glacial and bedrock geologic map products and databases for Marion County, Indiana

Abstract
The Internet has become a medium of choice for delivering geologic information to both technical users and the general public. The Indiana Geological Survey (IGS) is creating a Web-based glacial and bedrock geologic map site for Marion County in central Indiana to provide detailed geologic information needed to address environmental and resource management issues related to a growing population and land-use conflicts. Marion County is the location of Indianapolis, the state capital and largest city. The IGS anticipates that the information available via the Web site will be widely used by the general public, industry, and government entities concerned about the geology, groundwater, and other natural resources in this county. 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 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.
