Drone-based mapping of Sassendalen for reindeer counting in Svalbard

This database contains a series of drone-based aerial images that were collected for the purpose of counting reindeer. The survey area consists of six transect lines in Sassendalen, each with a width of ca. 1.2km. Flights were taken with a DJI Mavic 2 Enterprise at an altitude of 120m during mid-July 2021. The coordinates of the transects are listed in the readme file, along with the survey area size. While these images have been collected for the purpose of counting reindeer, the data may be reused for other purposes, e.g. for generating digital elevation models or orthomosiac photo maps. Such features may be added in a future update of this dataset. Data were obtained in a joint project between the Svalbard Integrated Arctic Earth Observing System (SIOS), the University Centre in Svalbard (UNIS), the Norwegian Polar Insititute (NPI), and with support from the Norwegian University of Science and Technology (NTNU).

本数据库收录了一系列用于驯鹿计数目的的无人机航拍图像。调查区域位于萨森达伦，包含六条横断面线，每条横断面线的宽度约为1.2公里。图像采集于2021年7月中旬，使用DJI Mavic 2 Enterprise无人机在120米的高度进行飞行。横断面的坐标记录在readme文件中，同时包含调查区域的大小。虽然这些图像是专门为计数驯鹿而收集的，但数据可用于其他目的，例如生成数字高程模型或正射影像图。此类功能可能在数据集未来的更新中添加。数据由斯瓦尔巴综合北极地球观测系统（SIOS）、斯瓦尔巴大学中心（UNIS）、挪威极地研究所（NPI）联合项目获得，并得到挪威科学和技术大学（NTNU）的支持。
