A 2011 grant from IndianaView funded the digital archiving of the 10,020 public-domain maps and 1,497 copyright-restricted maps that represent 305 different Indiana locations. The ISDP provides access to more than 20 terabytes of Indiana geospatial data and most datasets are available to the public for download with no use restrictions. IU's high-performance networks and computing infrastructure support the ISDP, which archives and provides Web access to imagery provided by data partners within and outside IU.
Sanborn maps offer researchers and the public detailed information regarding town and building information in approximately 12,000 U.S. towns and cities from 1867 to 1970. Rich in historical data, each collection includes a decorative title page, an index of streets and addresses, a 'specials' index with the names of churches, schools, businesses, and a master index indicating the entirety of the mapped area and the sheet numbers for each large-scale map.
Other general information includes population, prevailing wind direction, outlines of each building and outbuilding, street and sidewalk widths, fire walls, natural features like rivers and canals, railroad corridors, building use, house and block number, the strength of the local fire department, indications of sprinkler systems, locations of fire hydrants, location of water and gas mains and even the names of most public buildings, churches and companies.
