About the GAC

The Geospatial Analysis Center (GAC) at the University of Minnesota Duluth is a student workforce-driven geographic information systems (GIS) services organization with statewide visibility and relevance. GAC has a decade-long record of external contract work with state agencies, counties, and regional organizations. The Center's staff also provide assistance in classrooms and research projects across campus. GAC supports the UMD GIS program by raising its visibility and demonstrating high-quality consulting services as well as supporting the development of a workforce that is well-prepared for graduate school and the GIS industry.

Services may include project design, identification of system and data needs, data acquisition, budget estimates, analysis or oversight of a project. Data storage and hardware checkout is also available. The Center is also a resource for technological advancement information in the fields of remote sensing, geographic data analysis, and global positioning systems.


GAC maintains three virtual data servers that provide data storage and web-mapping software. A 6-terabyte server provides file storage for the spatial data library, student workspaces (including GIS academic program students), and password-protected project directories. A second virtual server hosts ArcGIS Server /Portal software and production applications and live web services and an identical server provides the ArcGIS Server development environment for teaching and research projects. GAC benefits from local stores of DNR data and the DNR application “Quicklayers” to access these data.  Additional partnerships with the City of Duluth and St Louis County allow easy access to public data for research and class projects.

Virtual desktops are also available for overnight or intensive processing as needed. Peripheral hardware available includes a large format printer (44”), Trimble GeoXT GPS, 12 Trimble Juno GPS units with ArcPad, and portable hard drives.

GAC now has a Trimble R1 available for checkout. The Trimble® R1 is a rugged, compact, lightweight GNSS receiver that provides professional-grade positioning information to any connected mobile device using Bluetooth® connectivity. For more information, please contact Steve Graham at steveg@d.umn.edu.

The Center utilizes a variety of GIS software packages in addition to specialty image analysis, mapping, digitizing, graphics, and presentation software. GAC benefits from the system-wide Esri software site license, which provides access to almost all of Esri’s software for academic use. UMD faculty and students can request Esri software hereFind information about access to all University spatial software here.
