Roads

[milkshake333]

I want to create something, that makes it able to assign names to roads. Those roads hold all coordinates, with a difference of 5 units, or something. I created a command to save paths, it will save it to xml files. The problem is that such a file gets to big and it gets laggy. So my question is, is there somebody who knows a nice way to do such a thing?

I want to use it for GPS, like in GTA IV. It really points you to where to go, not just a marker on your map(I know how to do this). And I want to use it for speedlimits(I know how to do this too).

It's just the way of saving and loading the streets I want to know about .

save it in sql.

xml can be slow when its huge (especially writing/modifying huge xml are painful)
