More [Canadian] High-Resolution Lidar [HRDEM] And Elevation Data Now Available
--
https://natural-resources.canada.ca/science-data/science-research/geomatics/more-high-resolution-lidar-elevation-data-now-available <-- shared technical press release
--
“... In this first article, highlights include:
• HRDEM & HRDEM Mosaic - over 709,000 km² of new LiDAR-derived elevation data added since May 2024, increasing coverage by 54%. This product now covers 244 of Canada’s 250 largest cities, and over 95% of the population.
• Northern HRDEM data - fully updated using ArcticDEM v4.1, improving quality for the entire Canadian Arctic.
• Automatically Extracted Buildings - Added 61 new projects and over 2.58 million building footprints, bringing the total to over 13.6 million.
• LiDAR Point Clouds - Expanded by over 200,000 km2, now totalling close to 364,000 km²…”
