Lake Simcoe Shoreline Inventory Inventaire des rives du lac Simcoe

Coordinate system: NAD83(CSRS) / UTM zone 17N (EPSG:2958)

The Lake Simcoe Shoreline Inventory 2008/2009 data was compiled by the Ontario Ministry of Natural Resources (OMNR) utilizing the 2008 or 2009 orthophotography available for Lake Simcoe as the main source of information. The objectives for compiling an inventory of the Lake Simcoe shoreline were to 1) better understand the current state of the shoreline, 2) track changes over time, if the inventory is repeated in the future and 3) assist in identifying priority areas for restoration. In 2015, the Provincial Geomatics Service Centre (PGSC) in Peterborough updated the shoreline mapping for Lake Simcoe. The shoreline mapping methodology which had been previously used, was revised by reducing the number of shoreline classifications and simplifying the attributes being captured. Orthophoto imagery (2013) was used as the digitizing base, while oblique imagery, taken late fall 2014, was used to assist with shoreline feature interpretation. Attribute fields were added to facilitate change detection analysis with previous shoreline mapping efforts, which had been based on 2008/2009 orthophoto imagery. The shoreline was mapped using a combination of linear shoreline features, shoreline alteration footprints, and offshore features. The eight shoreline classifications were further grouped into a natural, altered, or beach/bar class. Several partners were involved with the project, including: Ontario Ministry of Natural Resources and Forestry, Environment Canada, Ontario Ministry of the Environment and Climate Change, Severn Sound Environmental Association, Nottawasaga Valley Conservation Authority, Lake Simcoe Region Conservation Authority, and County of Simcoe. Purpose: The Lake Simcoe shoreline mapping was updated to fulfill the Ministry of Natural Resources and Forestry's (MNRF) obligations under the Lake Simcoe Protection Plan to monitor change in natural and altered shoreline.
