Digital terrain model (DGM) - flight 2019, Muskau

The digital terrain model describes the terrain surface through a regular dot grid. From each grid point, the location and height are known. The update will take place from 2020/2021 in a 6-year cycle, but in new lot definitions as in the present case.

数字地形模型（Digital Terrain Model）通过规则点网格表征地表形态。每个网格点均存储有对应的位置与高程数据。该模型的更新周期为6年，更新工作将于2020/2021年度启动，但本次更新将采用如本案例所示的新地块划分方案。
