Dom — Digital surface model

The digital surface model (DOM) describes the earth’s surface with all natural (e.g. vegetation) and artificial objects (e.g. buildings). The DOM is available in the form of an even grid with a grid width of 1 m in blade section 2 km x 2 km. A buffer of about 250 m is enough to reach the state of Brandenburg.数字表面模型（Digital Surface Model，DOM）可用于描述地球表面涵盖的所有自然地物（如植被）与人工地物（如建筑物）。该数据集以规整栅格形式提供，单幅栅格幅面为2千米×2千米，栅格单元宽度为1米。仅需设置约250米的缓冲区即可覆盖勃兰登堡州（Brandenburg）范围。
