ArcticDEM 32 m Mosaic

Dataset Summary

A publicly-accessible digital elevation mosaic covering the Arctic region, derived from the Polar Geospatial Center’s ArcticDEM project, at 32 m horizontal resolution.


📘 Dataset Description

  • Source
    Provided by the University of Minnesota’s Polar Geospatial Center (PGC), part of the ArcticDEM initiative funded by NSF & NGA (website).

  • Spatial Coverage
    Pan-Arctic: regions north of ~60° N (Greenland, Canada, Russia, Alaska, etc.).

  • Resolution
    Mosaic tiles at 32 m pixel spacing derived from 2 m strip data.

  • Temporal Context
    Mosaics built from multi-date strip DEMs, assembled via median-stacking; the 32 m product is a static mosaic without temporal layers.

  • File Format & Projection

    • Format: 32-bit GeoTIFFs
    • Projection: NSIDC Polar Stereographic North (EPSG:3413)
    • Vertical datum: WGS84 ellipsoid
  • Data and Quality Bands

    • Elevation band
    • Optional quality masks (source count, med-abs-dev)
    • Voids flagged with NoData (–9999)

🔧 Supported Tasks

  • Regional elevation modeling
  • Terrain analysis (gradient, aspect, watershed)
  • Large-scale environmental and geospatial modeling
  • Baseline surface for Arctic research & visualization
