Hello, I am working with v.net.path in Grass 6.4.0RC7. I am attempting to get the shortest distance between a point and numerous other points along a network of streets. I have point A going to 112 different point Bs. I created a text file that looks like this and is loaded into GRASS as the file containing the start and end points:
0 747212.685926 4720037.13823 746483.659225 4716904.53527 1 747212.685926 4720037.13823 746500.601921 4716933.7664 2 747212.685926 4720037.13823 746511.948724 4716964.86195 3 747212.685926 4720037.13823 746520.848479 4716995.63643 4 747212.685926 4720037.13823 746516.776154 4717023.48178 5 747212.685926 4720037.13823 746546.774411 4717037.56583 6 747212.685926 4720037.13823 746573.881945 4717057.02371 etc... It seems like the path works for some start and finish point combonations, but for others it does not and it simply draws a straight line between point A and point B (see image below). I am hoping someone might be able to tell me why this may be happening and how I can stop this from happening. The coordinate system I am using is in US feet and I am using a Maximum Distance to Network of "1" because all of the points should fall essentially right on the line. Thank you very much for any help you can lend. http://osgeo-org.1803224.n2.nabble.com/file/n5496931/Grass_Window.jpg -- View this message in context: http://osgeo-org.1803224.n2.nabble.com/Shortest-Distance-v-net-path-tp5496931p5496931.html Sent from the Grass - Users mailing list archive at Nabble.com. _______________________________________________ grass-user mailing list grass-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/grass-user
