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.
After the LiDAR data is obtained, the data can be post-processed only after data preprocessing. After the data preprocessing, there is a data checking software to conduct a preliminary check on the data results. The general data format check has the follo
Lidar (light detection and ranging) is an optical remote-sensing technique that uses laser light to densely sample the surface of the earth, producing highly accurate x,y,z measurements. Lidar, primarily used in airborne laser mapping applications, is eme
LIDAR (Light Detection and Ranging) technology and processing is used in a wide range of research and practical applications. With its ability to measure dimensions, distances, textures, and many other aspects of targeted subjects, LIDAR processing has be
