What is the best method for adding custom data. For example vector files for roads and power lines. Classification data for trees.
- Best place to source this.
- How to get this data to work and load with cesium.
If anyone could help me that would be great.
Support for data source such as point/lines/polygons through GeoJSON, KML, or other similar files is on the roadmap (See Support vector files (KML, SHP, CZML, GeoJSON) · Issue #628 · CesiumGS/cesium-unreal · GitHub).
