I am not <BR>> alone :).<BR>> I am doing some GIS stuff and have a question.<BR>> I am trying to develop some algorithm similar to dijkstra, and have <BR>> finished debugging with my testing hand-built graph. Now I want to test this <BR>> algorithm with real map data.<BR>> The problem is I don't know how to convert a map data(e.g. shape file) to a <BR>> data structure(like graph node matrix/linked list) I can use. Is there any way <BR>> or software I can use? Can anybody give me any hint? Thanks a lot.<BR>> <BR>> <BR>> Shawn Zhu.<BR>> July 16, 2007<BR><BR><br /><hr />See what you’re getting into…before you go there. <a href='http://newlivehotmail.com' target='_new'>Check it out!</a></body>
