Numerical Model Covering Area, M-34-49-D-d-1-1

The numerical Model of Territory Coverage refers to the surface of the terrain along with elements that protrude above it — natural and artificial elements. This product is developed in 2010 on the basis of aerial laser scanning.地表覆盖数值模型（Territory Coverage Numerical Model）指地形地表以及突出于其上方的自然与人工地物要素。该模型于2010年依托航空激光扫描技术研发完成。
