Explv provides an excellent tool for browsing the world map.

World Structure

The world is structured as follows:

Structure	Size	Description
Region	64x64	A portion of the game map.
Chunk	8x8	A portion of a Region.
Scene	104x104	The portion of the map that is currently loaded.
Coordinate	1x1	A position on the map.

In the image above, the blue grid represents Region borders, and the shaded light blue square represents the loaded Scene. Scenes span multiple regions, but do not necessarily fully enclose all of those regions. The large white numbers are region IDs, which can be resolved using any coordinate contained within that region:

y / 64 | ((x / 64) << 8)

For example, using the Lumbridge teleport spot (3221, 3219):

(3219 / 64) | (3221 / 64) << 8
= 12850
