Changelog:
Version 3.2.1 - February 2026 - Data available up to 2023.
Version 3.2 - May 2025 - Version updated with more data (historical compilation of Beaufort Delta) and updated attribute data.
Version 2.1 - November 2024 - first version of compilation used to test image server.
<div style='text-align:Left;'><div><p><span>Compilation of historical and recent hillshaded digital elevation models (bare-earth terrain models) derived through Light Detection and Ranging (LiDAR) data of the Northwest Territories. The compilation represents georeferenced coverage of very high resolution data (1 m spatial resolution) of NWT communities, infrastructure corridors, and other areas of interest. Hillshaded digital terrain models (HS-DTM) represent a grayscale three-dimensional representation of the surface topography (bare ground) excluding vegetation and human objects such as buildings. Models were derived from LiDAR pointclouds at 1-m spatial resolution. LiDAR vendors may have performed positional adjustments based on ground control points where necessary based on project requirements.</span></p></div></div>
