EarthDEM - Mosaics, Version 1

The EarthDEM Project provides high-resolution digital surface models (DSMs) for mid-latitude (non-polar) regions using optical stereo imagery, high-performance computing, and open-source photogrammetry software. This record represents the DSM mosaic dataset, version 1, built from over 20 years of photogrammetrically-derived elevation data.地球DEM项目（EarthDEM Project）采用光学立体影像、高性能计算及开源摄影测量软件，为中纬度（非极地）区域提供高分辨率数字地表模型（Digital Surface Models, DSMs）。本数据集为版本1的DSM拼接数据集，基于超过20年的摄影测量衍生高程数据构建而成。
