Dataset of 10 Nov 2022 to assess the geometric and radiometric accuracy of Micasense Altum multispectral imagery

The surveyed area is a shrubland, with approximately 0.21 km2, naturally recovering from a wildfire, with no post-fire management. The dominant vegetation consisted of Cistus ladanifer and Arbutus unedo, with patches of pine trees 1 to 2 meters high and some Eucalyptus globulus. The area is at an altitude of approximately 295 m a.s.l., and the terrain topography has gentle slopes. The aerial survey using UAS was carried out on two consecutive days (November 10 and 11, 2022) with the Micasense Altum AL0 AL04-1916156-SC. This dataset was used to determine the geometric and radiometric accuracy of the UAS, and the main findings will be used in a scientific publication (submitted; details will be added upon acceptance for publication).

本调查区域为灌丛地，面积约0.21平方千米，处于野火后自然恢复阶段，未实施任何火后管理措施。区域内优势植被为岩蔷薇（Cistus ladanifer）和草莓树（Arbutus unedo），分布有高度1至2米的片状松林，以及部分蓝桉（Eucalyptus globulus）。该区域海拔约295米（a.s.l.），地形坡度平缓。本次研究依托无人机系统（Unmanned Aerial System，UAS）搭载Micasense Altum AL0 AL04-1916156-SC型设备开展航空测量，作业时间为2022年11月10日至11日，连续两天完成。本数据集用于测定该无人机系统的几何与辐射精度，其核心研究成果将发表于一篇已投稿的学术期刊论文（录用后将补充完整细节）。
