If you are looking for an algorithm it's using the harvesine forumula or a quadtree data structure. A quadtree or a r-tree in maps applications most likely it uses a space-filling-curve to sort the quadtree. If you look for sfc I recommend a hilbert curve because it has better space fill quality but normally they uses a z-curve.
