A little machinery behind this page: map, height view and point cloud.
What loaded
Open a view to see what actually loaded.
Maps
Map views are stitched top-down images. Large ones are served as tiles so zooming in asks for detail only where you are looking.
That is why a map can open quickly and still have sharper pieces waiting deeper in the zoom.

Height maps
Terrain views use height data to show shape: slopes, bumps, gaps, and the places where reconstruction gets suspicious.
When a richer terrain package exists, it streams in smaller pieces. Useful for looking closer. Not a survey claim.

Point clouds
A point cloud is the scene as many colored points instead of a solid mesh. It is good for seeing what the reconstruction actually measured.
Public clouds use streamable tiles when available, so the browser loads the part you are looking at instead of one huge source file.

Why choices exist
One file does not fit every screen and connection. Browse stays light; inspect spends more when you ask.
