Cartographic information is increasingly stored as digital data. There are enormous advantages to this form of storage. Maps based on digital data can be updated or redesigned with a few keystrokes. Map users can control such elements as scale and color; can include only such information as they are interested in; and can use a "geographical information system" (GIS) to combine data from several different sources in one map.
The University of Chicago Map Collection has acquired a great deal of cartographic information in digital form as well as some software and hardware with which users may view and print maps generated from these data.
The following pages contain a description of parts of the Collection's holdings as of mid-2012. Many additional holdings can be found in the Library's on-line catalog by doing a keyword subject search on the genre/form term "Geospatial data" or a combination of the form subdivision terms "Maps" and "Databases." A huge amount of geospatial data can also be downloaded for free.
Please note that, with some exceptions, the Map Collection's paper map holdings can usually provide spatial information in greater detail and for a wider variety of periods than its holdings of digital cartographic data. Digital cartography typically works best for the production of thematic maps and relatively simple general maps. It is possible to georeference paper maps and to use the files as "raster" data, or, with considerably more effort, to compile vector data files from them.

Many users print out maps on the Map Collection's HP 7000. This machine prints reasonably high-quality 8-1/2 x 11 inch or 11 x 17 maps.
Most mapping programs will generate electronic files containing cartographic data. Users are free to download data. The Map Collection has a CD burner, and its computers are equipped with USB ports into which you may plug flash drives. Alternatively, you can e-mail yourself smaller files. Another possibility is exporting your file into a graphics program with more flexible drawing capabilities than the mapping programs. Adobe Photoshop is available at the Map Collection. Note that not all mapping programs generate the same types of export files and that drawing programs vary in their ability to deal with files of different types.
