Image-based Digital Surface Model (bDOM)

The image-based digital surface model (bDOM) depicts the surface of the earth, including the objects on it, such as buildings and vegetation with a lattice width of 20 cm. The surface model also contains moving objects, such as cars or wings of wind turbines. The bDOM is delivered with a resolution of 20 cm. The height accuracy is ± 0.5 m. The provision fee depends on the size of the area requested.

基于图像的数字表面模型（image-based digital surface model，bDOM）可刻画地球表面及其上的各类地物，包括建筑物与植被，其格网宽度为20厘米。该模型同时涵盖移动物体，例如汽车或风力涡轮机叶片。该bDOM的空间分辨率为20厘米，高程精度为±0.5米。其获取费用取决于所申请区域的面积。
