The real-scene 3D model has both three-dimensional and real-scene characteristics. In the business work of natural resources, it has a wealth of spatial analysis applications and provides powerful data support for other industries.
According to the geographical location of the study area, the sunshine and shadow changes of the four seasons of the real scene 3D model can be evaluated by using the sunshine analysis function.

After the real-scene 3D model analyzes the filling and excavation of a certain place, it can evaluate the amount of filling and excavation required to level a certain range of ground surface, which greatly liberates the internal and external workload of engineering surveyors.

Guangdong Province is located in a (sub)tropical monsoon climate zone, where typhoons and rainstorms frequently occur. With the support of the real 3D model, we can intuitively and conveniently analyze and evaluate the submergence threat of heavy rain to low-lying areas, and formulate corresponding countermeasures early.

In recent years, Feiyan Remote Sensing has vigorously developed the 3D GIS field, and has undertaken projects such as 3D city modeling of Yiwu City, 3D city modeling of Huangshan City, 3D city modeling of Hefei City, acquisition and processing of LiDAR and oblique aerial photography data in Fuzhou City, etc. A large amount of production experience has been accumulated, and an industrial chain of data acquisition (oblique photography data, LiDAR data), data processing and processing, and 3D modeling has been formed.
