Comments Off on New Detailed Indianapolis Wall Map We now have a detailed wall map of the Indianapolis Area hanging in the Information Commons near the Reference Collection. It covers all of Marion County and the surrounding cities, such as Carmel, Noblesville, Brownsburg, and Greenwood. Every road and highway is depicted (unless it was just built in the last year or two).

Comments Off on USGS Releases free Topo Maps From a recent USGS Announcement:
The U.S. Geological Survey (USGS) Historical Quadrangle Scanning Project (HQSP) is in the process of releasing all editions and all scales of more than 200,000 historic topographic maps of the United States dating from 1884-2006.
For more than 130 years, the USGS topographic mapping program has accurately portrayed the complex geography of our Nation. The historical topographic map collection contains all editions and all scales of USGS topographic quadrangles. Files are high resolution (600 DPI) scanned images of all maps from the USGS legacy collection.
The historical topographic map collection includes all States and U.S. territories mapped by the USGS. The HQSP creates a master catalogue and digital archive for all topographic maps and provides easy access to the public to download this historical data to accompany topographic maps that are no longer available for distribution as lithographic prints.
Historical maps are available to the public at no cost in GeoPDF format from the USGS Store. These maps are georeferenced and can be used in conjunction with the new USGS digital topographic map, the US Topo.
Future plans include providing the historical maps in GeoPDF andGeoTIFF formats through The National Map in the fall of 2011. The GeoTIFFs can be imported into a Geographic Information System and overlain with other data sources.
