Numerical Model of Land, M-34-49-C-a-1-4

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.数值土地模型（Numerical Land Model）指不含任何突出于地形表面之上要素的地形表面，此类突出要素涵盖自然要素（如林木）与人工要素（如建筑物）。该数据集于2010年基于航空激光扫描（aerial laser scanning）技术开发而成。
