This is a very old term used to try to describe the Google Maps interface to people who never used an octree multidirectional scrolling and zooming image collection.
- boomlinde 5y agoI would have guessed that they use quadtrees for this, splitting each non-leaf node into quadrants of more detailed maps as you zoom in.
- incanus77 5y agoIt's a quadtree of sorts, but is typically done via map projection (web mercator) math so that each tile is replaced by four tiles at the next highest (more zoomed-in) zoom level. Number of tiles to cover the world at zoom z = 4^z
