ArcticDEM V3 2m Mosaic [deprecated]

  • ArcticDEM provides a high-resolution (2m) digital surface model (DSM) of the Arctic, including vegetation, buildings, and other surface features.

  • It is a joint initiative by NGA and NSF, created using optical stereo imagery and advanced computing techniques.

  • The dataset is available as a collection of strips due to projection differences, with mosaicked files offering blended coverage.

  • Users must acknowledge NSF and PGC in publications and research when using this dataset.

  • The dataset covers the Arctic region and is freely accessible for research, education, and non-profit purposes through Earth Engine.

Description

ArcticDEM is a National Geospatial-Intelligence Agency (NGA) and National Science Foundation (NSF) public-private initiative to automatically produce a high-resolution, high-quality digital surface model (DSM) of the Arctic using optical stereo imagery, high-performance computing, and open source photogrammetry software. It includes vegetation, tree canopy, buildings, and other man-made surface features. The 2m asset is a collection of strips rather than a single mosaic due to projection differences between strips.

Mosaicked DEM files are compiled from the best quality strip DEM files which have been blended and feathered to reduce void areas and edge-matching artifacts. Filtered IceSAT altimetry data has been applied to the raster files to improve absolute accuracy.
