This is the data from the aerial survey of the monastery area of Ihlow, district of Aurich, to locate archaeological structures on 22.06.2023 (NIhK activity 2023-4). The aim was to locate archaeological features. The photos were taken with a DJI Mavic3M drone with RTK module. The location was measured using Sapos HEPS correction data, resulting in a horizontal position accuracy of 0.01 - 0.02 m and a height accuracy of 0.02 - 0.03 m. The photos were calculated into an orthomosaic using Agisoft Metashape and exported as a multiband raster. The recorded bands correspond to Green (860nm +/-16nm), Red (650nm +/-16nm), Red Edge (730nm +/-16nm) and Near Infrared (860nm +/-26nm).
