I have citygml Lod2 data and 2D shapefile of buildings of same area. How best can I store these two data and integrate so I can query to get info from both the 3d and the 2d data when I visualize in a web application like cesiumjs?

Hi @dennis​ ,

It sounds like you might want to do a spatial join or join (if you have an id field). Once you have joined the data, you should just have to write to Cesium 3D Tiles (or use the CesiumionConnector method).

Joining the data should bring all of your attributes into a single model that can then be queried in Cesium.
