Canadian DEM (CDEM).

Introduction

The Canadian elevation model in its 0.75-arc-second resolution is a digital elevation model (DEM’s) produced by Natural Resources Canada (NRCan). CDEM is mainly based on elevation contours and hydrographic data from NRCan's Geospatial Data Base at the scale of 1:50,000, or at other scales provided by other provinces and territories. Temporal coverage is 1945-2011.

Please consult the product-specification (see link below) for more details.
