ÍslandsDEM v1.0 10m

Since 2015, elevation data from the Arctic (north of 60°N, including Iceland) started to be openly available through the ArcticDEM project, led by the Polar Geospatial Center, University of Minnesota (

This data consists of a large amount of Digital Elevation Models (DEMs) repeatedly acquired (multitemporal), typically from 2012-present, and the oldest data reaching back to 2008. The DEMs are derived from satellite sub-meter stereo imagery, particularly from WorldView 1-3 and GeoEye-1. The processing of the DEMs was done using SETSM, an open-source digital photogrammetric software, in the Bluewaters supercomputer (University of Ilinois). Each DEM has 2x2m resolution and a footprint of ~18x100km.

In a collaborative effort between the National Land Survey of Iceland, the Icelandic Meteorological Office and the Polar Geospatial Center, we developed methods to handle and process a large amount of data available for Iceland. The methods developed consisted of

  • Spatial adjustment of all the available DEMs, for homogeneity and consistency in the location of each individual DEM.

  • Robust mosaicking into one single DEM of Iceland, by taking advantage of the multi-temporal coverage of DEMs. Each pixel of the mosaic corresponds to a median elevation value from the possible elevations available from the ArcticDEM. More details on the dataset available here. This DEM is resampled for 10x10m resolution.
