There isn't any amrt way to use SHP to routing? I have to write application using various map format. Thus using the SHP should have option to routing and navigate. You will have to create a routing graph from the OSM XML (typical steps > include: identify ways you want to use, split them up between > intersections, compute lengths, eliminate unneeded extra nodes). > Have you ever seen some example code, or article that help to resolve this problem.

But the application should be independent from conneting to internet. When I decide to use the online routing engine, still can display map from shape file? I mean: I display map from shapefile, then request the service for list of roads beetwen points A and B, and then marked the road on my map.
