On April 07, 2011, the IndianaMap Atlas was updated.
The four layers that provide county-based framework data (including address points, street centerlines, land parcels, and governmental boundaries) have been updated. The layers were compiled from data maintained by various county agencies in Indiana, as part of the IndianaMap Data Sharing Initiative between Indiana Geographic Information Council (IGIC), Indiana Office of Technology (IOT), Indiana Geographic Information Office (GIO), Indiana Department of Homeland Security (IDHS), Indiana Geological Survey (IGS) and participating Indiana counties. The layers named Address Points (IDHS) and Street Centerlines (IDHS) can be found in the following folder: INFRASTRUCTURE > Roads. The layers named Land Parcels (IDHS) and Government Boundaries (IDHS) can be found in the following folder: DEMOGRAPHICS > Political & Other Boundaries.
NOTE: All four layers are also NOW AVAILABLE FOR DOWNLOAD in ESRI File Geodatabase format.
On April 04, 2011, New layers available for download
Although they are not available for viewing on IndianaMap, ten new geologic layers are now available for download from the Geology download page, in a section titled "Indiana Contributions to the National Geothermal Data System." http://inmap.indiana.edu/dload_page/geology.html
Eight of the new layers show geologic structure on bedrock stratigraphic units. These georeferenced IMG images show the elevation (feet above sea level) of the tops of the New Albany Shale (Devonian and Mississippian), the Silurian System, the Trenton Limestone (Ordovician), the Maquoketa Group (Ordovician), the Knox Dolomite (Cambro-Ordovician), the Mt. Simon Sandstone (Cambrian), and the Precambrian basement, as well as the base of the New Albany Shale. They were produced by scanning and georeferencing published paper maps, including U.S. Department of Energy Maps 800, 801, 811, 812, 813, and 814. The other two layers show the elevations of the first occurrences of the 3,000 and 10,000 PPM (parts per million) total dissolved solids boundaries. These TIF images were produced by scanning and georeferencing Plates 1 and 2 of Indiana Geological Survey Open-File Report 94-2.
