Description
These digital orthophotos provide a full-colour view of the Greater Toronto Area, as well as the Golden Horseshoe. These images were provided by Triathlon Mapping Corporation. The georeferenced orthoimages have the same accuracy as a 1:20,000 scale map. The resolution of these photos is 1 meter. For coverage areas and thumbnails, please see the index and links below, for the location of MrSID files. To find the individual TIFF images, please consult the TIFF index.
