Umbrotasvæðið á Fagradalsfjalli 2021-2023 / Fagradalsfjall Eruptions 2021-2023

IS:

Myndkort af atburðum sem hafa átt sér stað á Reykjanesi frá mars 2021 - sept. 2023 hafa orðið til í samstarfi Náttúrufræðistofnunar, Veðurstofu Íslands, Jarðvísindastofnunar og Almannavarnir, sem hluti af viðbragðsáætlunum, hættumati og rannsóknum.

Í öllum atburðum voru teknar loftmyndir og hæðarlíkön, útlínur hrauns útbúin ásamt myndkortum. Myndkortin eru aðgengileg í gegnum WMS þjónustu og á Umbrotasjá ( https://kortasja.lmi.is/mapview/?application=umbrotasja).

Orthomosaics of the events occurring on the Reykjanes peninsula, SW Iceland, in March 2021- September 2023 have been created in a collaborative effort between the Natural Science Institute of Iceland (Náttúrufræðistofnun Íslands), the University of Iceland (Háskóli Íslands), the Icelandic Meterological Office (Veðurstofa Íslands), and the Civil Protection (Almannavarnir) as part of the response plans, hazard assessments and research.

Upon each event, aerial photographs were collected and Digital Elevation Models (DEMs), lava outlines, and orthomosaics were produced of these events. The orthomosaics are available via WMS and in the Volcano Viewer webpage ( https://kortasja.lmi.is/mapview/?application=umbrotasja). The data was created and distributed typically less than one day after data collection.

Myndirnar voru teknar með Hasselblad A6D myndavél úr flugvéli. Myndirnar voru unnar með MicMac photogrammetric hugbúnaði, í þeim tilgangi að útbúa hæðarlíkön og myndkort.

The images were collected with a Hasselblad A6D camera from an aircraft. The images were processed with the MicMac and Agisoft Metashape (v.2) photogrammetric software, in order to create Digital Elevation Models (DEMs) and orthomosaics.
