Spatial Information Resources

This guide will help you find spatial data (with an emphasis on Geographic Information System (GIS) data), online maps, and static maps, as well as resources for teaching and learning with spatial information.

The Trinity Network Repository

Trinity University maintains a network repository for spatial data. Trinity campus base map imagery, a collection of state and local layers, and data purchased à la cart can be accessed there. Data for specific courses can also be stored and maintained on the repository.

The repository also serves as an access point for installing ArcGIS software on the Trinity Unversity ESRI site license.

To access the network repository, please contact GIS liaison Jeremy Donald.

Data on the campus repository:

City of San Antonio/Bexar County GIS data (projected to State Plane South Central Texas feet)
