Numerical Model of Land, M-34-49-A-c-1-1

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）指剔除地表上方所有凸起要素的地形表面，涵盖自然要素（如树木）与人工要素（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。
