2022 - Mosaic of High Resolution Digital Elevation Model (HRDEM) at 1m

The High Resolution Digital Elevation Model (HRDEM) Mosaic represents the current and continous coverage of high-resolution elevation data available in Canada. This version of the mosaic, available at a spatial resolution of 1 meter, is a combination of DEM data generated from airborne LiDAR data and available at this resolution. This data collection includes a digital terrain model (DTM) and a digital surface model (DSM) for the entire coverage. The mosaic product is referenced to the Canadian Geodetic Vertical Datum 2013 (CGVD2013). The data in this collection have been reprojected from the source reference system to the Canada Atlas Lambert projection (EPSG:3979). In case of overlap between data sources, pixel values are set according to the most recent source.

This third party metadata element follows the Spatio Temporal Asset Catalog (STAC) specification.
