3D landmarks and trees like Apple Maps

Apple Maps shows detailed 3D landmarks (hand-modelled buildings), trees and more realistic elevation in cities. ts-maps has extruded buildings (fill-extrusion), terrain and sky, but no landmark models or vegetation.

Scope

• Support glTF/GLB landmark models placed by coordinate, rendered in the WebGL building pass with occlusion of labels (BuildingOcclusion).
• Trees: instanced low-poly trees from OSM natural=tree points or landcover=wood areas where tiles carry them.
• Roof shapes where building tiles carry roof:shape.
• Keep performance budgets: LOD by distance, and nothing drawn at low pitch.
