The three-dimensional ecological environmental protection system is a set of solutions that are based on high-precision photographic images and three-dimensional models to assist the decision-making of ecological environment supervision, improvement and protection. The system assists the monitoring and protection of the ecological environment in terms of changes in water bodies, vegetation monitoring, and dynamic supervision of major areas of sewage discharge throughout the region.

1) Vegetation analysis
By analyzing and comparing the vegetation situation of Remote sensing images in different periods, the change of vegetation coverage in the time period is obtained through NDVI (normalized vegetation index) and visualized on the base map. The red part is vegetation reduction , The blue part of the vegetation increased. Observe the pollution from the side through the vegetation.
