1. Scholars GeoPortal
Scholars GeoPortal is an online data portal from the Ontario Council of University Libraries (OCUL) that offers search, discovery, visualize, and access to a variety of open and restricted (licensed) geospatial datasets covering Ontario and Canada. The geospatial data available from the portal can be downloaded and imported into GIS software for mapping and analysis purposes. Open datasets are accessible by all, while restricted datasets are available to students, faculty, and staff at Ontario universities (including UWindsor) for teaching and research purposes (non-commercial use only). You’ll have to login for off-campus access to restricted data using your UWindsor account.
See the Getting Started with Scholars GeoPortal video for an introduction, and the GeoPortal User Guide for detailed instruction for using the portal.
Note: Most geospatial datasets available from the Academic Data Centre can be accessed and downloaded directly using Scholars GeoPortal.
2. Academic Data Centre Geospatial Data HoldingsSome datasets restricted to University of Windsor affiliates are not available online. For these datasets, which includes data from the City of Windsor, Teranet parcel boundaries, and imagery, try searching the ADC Geospatial Data Holdings.
3. Open Data PortalAdditional datasets can be found online through various data portals, some of which are listed below. Many of these portals, particularly those of municipal, provincial, and federal governments, are making their data available under open data licenses.
