What elements need to be built for 3D modeling of smart cities? How long does it take to draw a picture? 3D visualization 3 d map

Three-dimensional modeling of a city in the southwest of China shows that the city is located in the slope zone where the plateau transits to hills and basins, with large topographic relief and complex landform types. The customer asked for oblique photography to get a panoramic view of the whole landform.

The research area of this project covers a total area of about 2 square kilometers, and the construction content is ground total factor modeling, which mainly includes: ground building modeling, road modeling, terrain modeling, water system modeling, traffic facilities and urban components modeling, green vegetation modeling, etc. It is necessary to complete land ownership data (cadastral data) and different types of three-dimensional model data, such as building model, road model, traffic facilities and urban parts model, and combine them into a basic geospatial framework database.

Full-feature geographic data frame map

In addition to outdoor scenes, there are indoor scenes. By constantly entering the hierarchy, you can learn more indoor space data. This is our platform advantage. Intelligent buildings, smart factories and digital ports all have benchmarking cases, which support indoor semantic and topological information such as query and analysis.

After we integrate all the basic geospatial framework data, we use? City Builder/Campus Builder+ThingJS+eCharts tools are combined to display geographic data in three dimensions.
