Greater Toronto Area (G.T.A.) and adjacent regions: orthoimagery (2002)

Description

These digital orthoimages provide full-colour aerial coverage of the Greater Toronto Area, Golden Horseshoe and other counties including Grey, Simcoe, and Kawartha Lakes. There is also separate coverage of Lambton County (west of Middlesex County). These images were flown in April 2002 by J. D. Barnes and provided to the Geospatial Centre by the Ministry of Natural Resources in October 2004. The 5-colour map below outlines the extent of the area for which these images are available and also illustrates the range in pixel resolution from 20 cm to 50 cm.

Please note that because not all the images are held locally, some must be downloaded from a remote server in Toronto. A detailed clickable index, prepared by the staff of the Brock University Map Library, provides the 11-digit tile identifier (e.g., 17 6320 48580) for each image. Please use this index to determine the tile identifiers for the images that interest you.
