EarthDEM

EarthDEM - 2m GSD Digital Elevation Models (DEMs) and mosaics from 2002 to the present. The EarthDEM project seeks to fill the need for high-resolution time-series elevation data in non-polar regions. The time-dependent nature of the strip DEM files allows users to perform change detection analysis and to compare observations of topography data acquired in different seasons or years. The mosaic DEM tiles are assembled from multiple strip DEMs with the intention of providing a more consistent and comprehensive product over large areas. EarthDEM data is constructed from in-track and cross-track ...

EarthDEM——2米地面采样距离（Ground Sampling Distance, GSD）数字高程模型（Digital Elevation Models, DEMs）及镶嵌数据集，时间覆盖2002年至今。EarthDEM项目旨在填补非极地地区高分辨率时序高程数据的供给空白。条带式DEM文件的时序特性可支持用户开展变化检测分析，并对比不同季节或年份获取的地形观测数据。镶嵌DEM瓦片由多条条带DEM拼接而成，旨在为大范围区域提供一致性更强、覆盖更全面的产品。EarthDEM数据由沿轨（in-track）与交轨（cross-track）...
