Provincial Digital Elevation Model (PDEM)
Represents true ground elevation across the province.
The Provincial Digital Elevation Model (PDEM) is a general-purpose dataset designed to represent true ground elevation where possible and is based on best-available data across the province. This dataset has not been conditioned for any specific application. Please see the User Guide below for more information.Zoom in on the map and click your area of interest to determine which package(s) you require for download.
Now also available through a web service which exposes the data for visualization and geoprocessing. The service is best accessed through the ArcGIS REST API, either directly or by setting up an ArcGIS server connection using the REST endpoint URL. The service draws using the Web Mercator projection. For more information on what functionality is available and how to work with the service, read the Ontario Web Raster Services User Guide.
