Greater Toronto Area (GTA) Orthophotography Project 2002: 10km coverage
Coordinate system: 26917 - "NAD83 / UTM zone 17N"Abstract:
The Greater Toronto Area (GTA) Orthophotography Project 2002 consists of over 26,000 one-square-kilometer tiles of orthorectified colour imagery for the Greater Toronto Area. The imagery features 20 cm pixels for Niagara, Hamilton, Halton, Peel, York, Toronto and Durham, 30 cm pixels for Simcoe, and 50cm pixels for Peterborough and Northumberland. The imagery was flown in the spring of 2002.
The 10km coverage was created by mosaicing together 1km orthophotos into 10km x 10km tiles and reducing the resolution to a common pixel size of 2m. The scope of this project did not include adjustment of colours from the original source images.
