Welcome to Mapping & GIS

GIS literacy is important to demonstrate spatial relationships and distances.  There are many software tools that map data and they are explained on the GIS Subject Guide.  Additional information about maps, atlases and spatial imagery is found on that Subject Guide which highlights government data sources.

What is a Sanborn Map?

"The Sanborn map collection consists of a uniform series of large-scale maps, dating from 1867 to the present and depicting the commercial, industrial, and residential sections of some twelve thousand cities and towns in the United States, Canada, and Mexico.
The maps were designed to assist fire insurance agents in determining the degree of hazard associated with a particular property and therefore show the size, shape, and construction of dwellings, commercial buildings, and factories as well as fire walls, locations of windows and doors, sprinkler systems, and types of roofs.
The maps also indicate widths and names of streets, property boundaries, building use, and house and block numbers. They show the locations of water mains, giving their dimensions, and of fire alarm boxes and hydrants."
