The orthomosaic of the Reykjanes eruption have been created in a collaborative effort between Nátturfræðistofnun Íslands, Landmælingar Íslands, Jarðvísindastofnun and Almannavarnir, as part of the response plan of the Fagradalsfjall eruption of 2021.

The images were collected with a Hasselblad A6D camera onboard of a plane, and processed with the MicMac and Agisoft photogrammetric software, in order to create Digital Elevation Models (DEMs) and orthomosaics. The orthomosaics were made available via WMS and in the Umbrotasjá webpage (https://kortasja.lmi.is/mapview/?application=umbrotasja) less than one day after data collection.
