ArcticDEM is a public-private initiative by the National Geospatial-Intelligence Agency (NGA) and the National Science Foundation (NSF) to produce a high-resolution digital surface model of the Arctic. The dataset includes version 3 mosaics and strip DEMs generated from optical stereo imagery using high-performance computing and open-source photogrammetry software. It was contributed by Claire Porter of the University of Minnesota.
Use Cases
- Modeling glacier and ice sheet dynamics based on high-resolution elevation data
- Analyzing Arctic terrain changes over time using the digital surface model
- Supporting climate and environmental research with detailed geospatial data for the polar region
Strengths
- Produced through a collaboration between the NGA and NSF, indicating authoritative sourcing
- Described as a high-resolution and high-quality digital surface model
- Generated using automated photogrammetry on optical stereo imagery
Limitations
- Description metadata is limited; actual data quality requires manual inspection after download
- Row count, file formats, and column-level documentation are absent
