Airborne data products of the Bayelva Basin, Brøggerhalvøya, Svalbard: DSM, RGB, NIR, and TIR orthomosaics (2020-09-13)

This dataset includes aerial survey data products from the Bayelva basin (Brøggerhalvøya, Svalbard), including a Digital Surface Model (DSM) with a spatial resolution 15 cm, red-green-blue (RGB) and near-infrared (NIR) orthomosaics with a spatial resolution of 10 cm, and a thermal infrared orthomosaic (TIR) with a spatial resolution of 50 cm. The products originate from aerial images taken on 13 September 2020 during the SeaIce Summer 2020 – MOSAiC campaign. These images were taken with the MACS-Polar20, an aerial camera system developed by the DLR on board the AWI Polar-6 aircraft. The flight lines were flown with >60% x-track overlap and >80% in-track overlap. We used Pix4D for the photogrammetric processing of the images into DSM and orthomosaics. During our quality control of the DSM, we removed areas with insufficient overlap. The resulting DSM covers approximately 7.7 km^2 within the Bayelva basin. […]

本数据集收录了贝耶尔瓦盆地（布罗格哈尔半岛建筑群，斯瓦尔巴群岛）的航空测绘数据产品，包括具有15厘米空间分辨率的数字地表模型（DSM）、具有10厘米空间分辨率的红绿蓝（RGB）及近红外（NIR）正射影像图，以及具有50厘米空间分辨率的红外正射影像图（TIR）。这些产品源自于2020年9月13日SeaIce Summer 2020 – MOSAiC活动期间所拍摄的航空图像。图像采用DLR研发的搭载于AWI Polar-6飞机上的MACS-Polar20航空相机系统拍摄。飞行航线具有超过60%的横跨重叠度和超过80%的纵向重叠度。我们对图像进行了Pix4D软件的光测处理，生成了DSM和正射影像图。在DSM的质量控制过程中，我们移除了重叠不足的区域。生成的DSM覆盖了贝耶尔瓦盆地约7.7平方公里的区域。
