The Map Library collects extensively in the areas of geographic information science and geographic information systems. Works on both topics can be found in the Library’s catalog by searching the subject : Geographic information systems.

A geographic information system is “a system of hardware, software, data, people, organizations and institutional arrangements for collecting, storing, analyzing and disseminating information about areas of the earth. (Dueker and Kjerne. Multipurpose Cadastre: Terms and Definitions . 1989). To be a fully-functioning GISystem, it must perform all of the operations necessary for data ingest and storage, manipulation and analysis, and output, and there always needs to be a purpose, a question to be answered, a query to be filled.  While many think of GISystems as only a way to manipulate data to create a map, outputs from a GISystem can be a single number (e.g., number of forested acres), a table (e.g., populations for all of the counties in Illinois), or a graphic such as a map.

Geographic information systems allow the combination of geographic/location data with attribute/theme data through computer-driven processes.The Map Library has a collection of geospatial data on CD-Rom . Much of this data, or newer versions of this data, may be available for download from websites devoted to geospatial data

Assistance with GISystems applications is available through the Library’s Numeric and Spatial Data Services

Geographic information science is the research field that underlies the creation and application of geographic information systems . GIScience encompasses theories,methods, technologies and data for understanding geographic patterns and relationships; it studies how geographic data is transformed into geographic information. The impacts of GISystem use on individuals and society as well as the impacts of society on GISystems are examined within GIScience as are foundational themes in geography and cartography. Broadly, there are five themes in GIScience: ontology and representation; computation; cognition; applications, institutions, and society; crosscutting themes (time, scale). ( Mark, 2003 )

The National Map
“The National Map is a collaborative effort among the USGS and other Federal, State, and local partners to improve and deliver topographic information for the Nation. The geographic information available from The National Map includes orthoimagery (aerial photographs), elevation, geographic names, hydrography, boundaries, transportation, structures, and land cover. Other types of geographic information can be added within the viewer or brought in with The National Map data into a Geographic Information System to create specific types of maps or map views.”
