ArcticDEM Mosaic [deprecated]

AI-generated Key Takeaways

• ArcticDEM V2 is a 5-meter resolution digital surface model (DSM) of the Arctic, representing first-return elevation, including vegetation and man-made features.

• This dataset is superseded by a newer version (UMN/PGC/ArcticDEM/V3/2m_mosaic) and is considered deprecated.

• ArcticDEM V2 data is mosaicked from strips, with some areas interpolated and others derived from stereo matching.

• Users must acknowledge the NSF and PGC when using this data in publications or presentations.

Caution: This dataset has been superseded by UMN/PGC/ArcticDEM/V4/2m_mosaic.

Description

ArcticDEM is a digital surface model (DSM) that portrays first-return elevation values that include 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.
