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
