Numerical Model Territory, M-34-49-A-d-4-3

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.数值地形模型（Numerical Land Model）指不含地表凸出要素的地形表面，所述凸出要素涵盖自然地物（如林木）与人工地物（如建筑物）。该数据集于2010年依托航空激光扫描技术研发完成。
