The 'id' should not be the string 'id', but rather a unique IDentifier for each point. Usually you will want to use a running number, so that the first is 1 the second is 2 etc... Here is an example of 2 lines: 1 242856.60 431305.07 242551.88 432149.70 2 242866.60 431325.07 242550.88 432140.70
Wolf, What you show above is the same two points on both lines. I changed the file 'nodes' to read: 1|242856.60|431305.07 2|242551.88|432149.70 The command line is: GRASS 6.4.0svn (oregonM):/usr4/grassbase > v.net.path in=abernethy_creek out=stream_length type=line file=/usr4/grassbase/nodes --o Yet I still see: ... Graph was built WARNING: Wrong input format: 1|242856.60|431305.07 WARNING: Wrong input format: 2|242551.88|432149.70 WARNING: [2] input format errors I tried using v.in.ascii to add those two points to a file named 'startend', but when I specified that map name it apparently was not added to the vector directory. What am I still doing incorrectly? Or, is there a different module that will return the distance along the stream vector map between those two defined points?
