蒙古30m分辨率数字高程模型（DEM）数据

本数据集基于国内外立体成像卫星数据成果进行优化、局部修正与纠偏，采取粗差修正、空值填充和水域数值异常剔除等处理方法，经过图像拼接、投影转化、裁剪等步骤，生成了优化的30m分辨率数字高程模型（DEM），数据成像数据为2019年。

This dataset is optimized, partially revised and rectified based on domestic and international stereoscopic imaging satellite data products. It utilizes processing workflows including gross error correction, null value filling, and elimination of anomalous numerical values in water areas, and undergoes procedures such as image mosaicking, projection transformation and cropping, ultimately generating an optimized 30-meter resolution Digital Elevation Model (DEM). The imaging data of this dataset was collected in 2019.
