The Map and Data Centre currently holds or has access to a wealth of geospatial data, ranging from very detailed local data to worldwide sources.

Data must be requested in person at the Map and Data Centre service desk and a release agreement must be signed. Western students, staff, and faculty will be required to present a valid Western ONECard to gain access to the data. Western students, staff, and faculty may also copy requested resources to a data storage device (ex. USB or external HD) for research or teaching use outside of the library.

The Map and Data Centre has workstations equipped with ArcGIS, QGIS and other software to explore/manipulate the data. Free online ArcGIS training via the ESRI Virtual Campus is available through the ArcGIS Site License for the Western community.

Please visit the Scholars GeoPortal website for a wide variety of Ontario and Canada geospatial data and imagery. For a listing of online databases, see our Geographic Information Systems (GIS) Research Guide.
