[mkgmap-dev] problems at map intersections?From Mark Burton markb at ordern.com on Sat Jul 18 10:43:43 BST 2009

An overlap of 300 meters sounds like a good idea for the > routing - but as said before, I'm saying this from a position of > blessful ignorance. I will answer this one for Steve: The inter-tile routing is accomplished by having a set of "boundary nodes" that have exactly the same coordinates in each of the tiles that borders the boundary. To route across tiles, it has to go via a boundary node. To ensure the boundary node coordinates are the same in both tiles, there is no overlap in the bounding boxes. Cheers, Mark
