Elevation data provides a detailed description of terrain and surface. The data are established as point clouds from airborne laser scanning or matching from aerial images. The point clouds have varying density (point/m²) for different purposes. From the point clouds, elevation models are generated on grid format of terrain (DTM) and surface (DOM).

高程数据（Elevation data）可对地形与地表进行精细化描述。该类数据可通过机载激光扫描或航空影像匹配的方式构建点云（point clouds）。针对不同应用需求，点云的密度（单位：点/平方米，point/m²）存在差异。基于此类点云，可生成格网格式的地形数字地形模型（DTM, Digital Terrain Model）与地表数字地表模型（DOM, Digital Surface Model）。
