#1045: strange behaviour in v.net.path ------------------------------+--------------------------------------------- Reporter: manuele | Owner: [email protected] Type: defect | Status: new Priority: normal | Milestone: 6.4.0 Component: Vector | Version: unspecified Keywords: network analysis | Platform: Linux Cpu: x86-32 | ------------------------------+--------------------------------------------- Dear developers, I found that giving a complete list of origins and destinations in a file I obtain a different result respect giving a single couple from the standard output. For example with the command:
> echo "26 4 9" | v.net.path am_net afcol=arc_cost out=myPathMap I obtain this result: "cat","id","fcat","tcat","sp","cost","fdist","tdist"[[BR]] "1", "26","4", "9", "0", "3.0", "0.0", "0.0" otherwise using the same network map with the different command: > cat am_od_pair.txt | v.net.path am_net afcol=arc_cost out=myPathMap for the same origin destination couple I obtain:[[BR]] "cat","id","fcat","tcat","sp","cost", "fdist","tdist"[[BR]] "26", "26","4", "9", "1", "1.79769313486232e+19","0", "0" where it even seams that the node 9 is not reachable. -- Ticket URL: <http://trac.osgeo.org/grass/ticket/1045> GRASS GIS <http://grass.osgeo.org>
