2012-2018年老挝区域资源三号卫星10米无控DSM数据

老挝区域约 23 万平方公里的无控10米DSM产品,是基于2012-2018年获取的该区域资源三号三线阵立体卫星影像，利用自主研发高分辨率卫星数据处理软件系统，通过去云补云多时相数据高精度测绘融合处理，生成的无控DSM数字高程模型数据，约23.0万km2，格网大小10米，高程精度优于3米。Uncontrolled 10-meter DSM product covering approximately 230,000 square kilometers of the Lao People's Democratic Republic region. This product is generated based on Ziyuan-3 three-line array stereoscopic satellite imagery acquired over this region between 2012 and 2018, using the independently developed high-resolution satellite data processing software system, and produced through high-precision surveying, mapping and fusion processing of multi-temporal data with cloud removal and cloud gap filling. The final uncontrolled DSM digital elevation model data has an area of approximately 230,000 km², with a grid size of 10 meters and an elevation accuracy better than 3 meters.
