Numerical Model Territory, M-34-49-D-a-2-4

Numerical Land Model refers to the surface of the terrain without elements that protrude above it — natural elements (e.g. treeing) and artificial elements (e.g. buildings). This product was developed in 2010 on the basis of aerial laser scanning.数值地表模型（Numerical Land Model）指地表之上不存在突出要素的地形表面，涵盖自然要素（例如树木）与人工要素（例如建筑物）。该数据集于2010年基于航空激光扫描技术研发而成。
