PDF maps


see the Google Drive links at right for PDF maps of the Ford Center (2020 aerial imagery background ) (2022 aerial imagery). These can be used in Avenza Maps for navigation. The Overview maps cover all of the Ford Center lands near Alberta. There are individual section maps available too.


If you are looking for Historic topographic maps, see topoView, run by the USGS. They have both current and historic topo maps available for download. You can search using a map interface, and filter results by map scale. Downloads are available in jpeg, GeoTiff (ArcGIS), KMZ (Google Earth), and GeoPDF (Avenza Maps) format. Click the topoView link, then View and Download. You can then view and search by location (using a location or map's name or a map interface), filter by map scale and date, and more.
