How this page delivers map, height view, 3D model and point cloud.

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 as small 3D pieces. It is useful for inspection, not a claim that the scan is survey-grade.

3D models
Most 3D views come from photogrammetry: photos turned into a textured mesh. The page starts from a saved camera angle so the object opens in a readable pose.
Lighter and sharper model rungs are separate. Texture labels only appear when that format is actually published.

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 there are choices
There is no single perfect file for every screen, browser, and connection. Browse stays light; inspect spends more only after the page has a reason.
These details show what the page can actually load, so the controls stay honest.
