资源简介：
归一化植被指数在研究植被长势、地物分类方面有重要作用。本数据集为2019年植被生长季逐月的黑河流域典型站点无人机遥感NDVI（Normalized Differential Vegetation Index）数据，空间分辨率为0.2 m。NDVI数据获取流程为将无人机拍摄后的单幅影像通过pix4D mapper进行拼接，并由pix4D mapper自动进行拼接后影像的植被指数计算。最后将pix4D mapper拼接的单航次影像利用ArcGIS镶嵌得到整个飞行区域影像。
The Normalized Difference Vegetation Index (NDVI) plays a critical role in vegetation vigor assessment and land cover classification. This dataset contains monthly unmanned aerial vehicle (UAV) remote sensing NDVI (Normalized Differential Vegetation Index) data for typical sites in the Heihe River Basin during the 2019 vegetation growing season, with a spatial resolution of 0.2 m. The NDVI data acquisition workflow is as follows: first, individual images captured by the UAV are mosaicked using Pix4D Mapper, and the vegetation index calculation for the mosaicked images is automatically executed by Pix4D Mapper. Finally, the single-pass imagery mosaicked by Pix4D Mapper is processed via ArcGIS to generate the complete flight area image.
