Will keep looking into fixing the projections of the buildings for the cesium layer. I have switched over to using the add_terrain function for 3D terrain which is looking great...

Deck.gl has recently added a terrain extension to allow 2D layers to generate across the 3D surface. Would is this something that could be integrated into mapdeck? https://deck.gl/docs/api-reference/extensions/terrain-extension
