Description: Colour aerial photography at 1 : 10 000 scale of the Regional Municipality of York, Ontario taken in the spring and created by Triathlon Inc. The colour digital orthophotography and digital terrain data was developed from these images. Orthophotographs combine the image characteristics of the photograph with the geometric qualities of a map. Orthophotography was developed for the entire region. The digital orthophotographs have a 20cm ground pixel resolution and were subdivided into 1 kilometre by 1 kilometre tiles and were delivered in georeferenced Geotiff image files. The image tiles are horizontally referenced to 6 degree UTM projection and NAD -83 datum. Vertical control datum is referenced to mean sea level as Bench Marks established by the Geodetic Survey of Canada (CGVD28). The images were later combined by municipality and converted into nine MrSid format images covering the entire region.
