Unmanned aerial vehicle imagery on desert grassland

We acquired an aerial image dataset for April 2021. The quadrotor M300 RTK UAV (DJI-Innovations, Shenzhen, China) was selected as the data acquisition platform. To satisfy the aerial photography requirement, the forward and side overlaps were set to 70% and 80%, respectively. Each image was 5280 × 3956 pixels in size and comprised three bands in the RGB domains, with a radiometric resolution of 24 bits.Features exported from eCognition Developer 64 and python code for features selection are provided.本次研究获取了2021年4月的航空影像数据集。本次数据采集选用大疆创新（DJI-Innovations，中国深圳）研发的四旋翼M300 RTK无人机（Unmanned Aerial Vehicle, UAV）作为平台。为满足航空摄影作业需求，分别将航向重叠度与旁向重叠度设置为70%和80%。单张影像分辨率为5280×3956像素，包含RGB（Red Green Blue）三个波段，辐射分辨率为24比特。本数据集还提供了从eCognition Developer 64中导出的影像特征，以及用于特征选择的Python代码。
