Height data NDH Blåmannsisen-north 4pkt 2015

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).

高程数据可详尽刻画地形与地表特征。该类数据通过机载激光扫描生成点云，或通过航空影像匹配得到点云。针对不同应用场景，点云的点密度（单位：点/平方米）存在差异。基于上述点云，可生成格网格式的数字地形模型（DTM, Digital Terrain Model）与数字地表模型（DOM, Digital Surface Model）。
