Footprints of MACS aerial images from POLAR 6 ThawTrend_Air_2019 flight campaign in northern Alaska (US)

Nitze, Ingmar; Grosse, Guido; Gessner, Matthias; Sachs, Torsten

This datasets contains the footprints of the DLR MACS (Modular Aerial Camera System) acquisitions (RGB + NIR) during the AWI ThawTrendAir2019 campaign on POLAR 6 from 10 July until 1 August 2019. This mission was based in Utkiagvik/Barrow, Alaska, USA. The aerial images were acquired to map permafrost related land cover and landforms in very high resolution and to create multi-spectral orthomosaics and digital surface models (DSM) across the Arctic Coastal Plain (North Slope) of Alaska. The acquired datasets cover grids of specific targets (e.g. coastal erosion, fire scars, permafrost degradation) as well as transects. The footprint files were created to search for data availability and data selection purposes. Data were extracted from raw MACS files using DLR MACS-BOX Mosaica Software and processed with custom python scripts (
