This layer contains elevation contours at 25 cm intervals, covering the Lake Simcoe Watershed. The contours were generated using the ESRI Contour tool from a 2023 Digital Elevation Model (DEM) with 50 cm resolution, and subsequently simplified with a 25 cm tolerance. The layer is displayed with filter for 50cm, 1m and 5m contour lines.
