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
