Most maps are available for check out and for inter-library loan to other libraries.
Atlases are stored in the Library Service Center, and can be requested for in-Library use via the Library Catalog.


Spatial and Attribute Data Resources for GIS at Georgia Tech

The Georgia Tech library has several print resources for practical GIS and remote sensing applications. Useful subject headings include "geographic information systems", "remote sensing", and "geodatabases", and call numbers G70.2 and G70.3

Researching GIS
GeoBase and GeoRef are the launching point for conducting a review of the scholarly literature related to GIS. Scholarly journals in the field include Transactions on GIS and the Journal of Geographical Systems The library catalog will also be helpful in identifying monograph holdings.

Data Sets
There are several sources of geospatial and attribute data, including your own data sets, government and commercial resources. The links to the left will break down several data set sources by scope: national, state, and international. Be aware that while many data sets are free, several, including some federal data sets, are only available for a fee. As a Federal Depository Library, the GT Library also receives some GIS data on CD and DVD, while several key sources are mentioned, the library catalog will provide a full listing of a variety of reports and data series from several federal agencies.

Attribute data sets are also very useful, particularly in thematic mapping and data analysis. Attribute data might not be available in a spatial form, but many federal sources will include FIPS codes for information captured at a geographic entity like the county level. These codes will allow you to join this attribute data to existing spatial data.

When obtaining GIS data, remember that different agencies and companies will use different protocols for creating and making the spatial data available. The GIS software that you are using may be able to read some data formats and may be able to import others. Be aware of the metadata that accompanies the dataset which can help you determine the sources of the data, copyright restrictions, and the recency of the data. When combining data from multiple sources also be aware of the following:

  • Does the scale of the data match your other data sets?
  • Does the coordinate system of the data match?
  • Are the data projected in the same way?
  • What level of summary data is available (e.g. county, state, etc)?

Learning GIS
There are several web based tools for learning GIS.   A great list is available here.
Georgia Tech's School of City and Regional Planning also offers several courses in GIS.
