Description: The regional boundary indicates the jurisdiction between York Region and neighbouring regions. The municipal boundaries define the limits of the Region's nine area municipalities: Aurora, East Gwillimbury, Georgina, King, Markham, Newmarket, Richmond Hill, Whitchurch-Stouffville and Vaughan. In 2007 an extensive investigation and clean-up of the municipal boundary locations was completed which included: snapping the boundaries to the road centrelines (which were spatially adjusted to the orthophotography in 2005); recalculating the boundary along Highway 404 to follow the 150 feet west of the centre line of the highway as outlined in the 1970 Regional Municipality of York Act; spatially adjusting the boundary along the Holland River to coincide with the centre of the river as illustrated in the 2005 orthophotography; spatially adjusting the boundary along Lake Simcoe according to the recent corrections completed by the Lake Simcoe Regional Conservation Authority according to the 2002 orthophotography; and several areas often questioned by users of the municipal boundary data were clarified in cooperation with the local municipalities.
Description: Colour aerial photography at 1:10 000 scale of the Regional Municipality of York, Ontario taken in between April 7 - 27th, 2023 by First Base Solutions Inc. Colour digital orthophotography 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 2023 digital orthophotographs have a 10cm ground pixel resolution. The 2022 digital orthophotos 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.
