Smart city development process review
(It is not very professional to explore the summary and combing related to UE smart city. Please correct me if there are any mistakes.)
1. GIS data acquisition:
Obtain from Google Maps, geographic data websites, etc., or use third-party software to download (Shuijingzhu GIS, ESRI's ArcGIS online, Cesium's ION)
2.GIS data processing and generation model:
The first category: Esri CityEngine: Write CGA (script) rules in the RPK rule package, which can then be exported to UE
The second category: Cesium:
The third category: Supermap Supermap: SupermapSDK for UnrealEngine
The fourth category: modeling software to process GIS data: MAX/MAYA/BLENDER/C4D, etc., install corresponding plug-ins
Various differences: the GIS data standards used may be different (three OGC standards: Cesium's 3D Tiles, SuperMap's S3M and ESRI's I3S standards), and their respective fully automatic scene generation algorithms are different .
3. The city model is imported into UE for secondary development:
In terms of models, landmark buildings or important buildings can be replaced with artificial high-model ones.
