as just mentioned on the -user list I've added a coor= option to d.path,
making it (optionally) non-interactive. Hopefully the GUI gods and real-
time Gpsd coders can do something neat with it now.
one lingering question is what to set the maximum search distance to. It
tries to lock onto a node in the vector map (eg road intersection or
v.lrs street address node). Currently maxdist is set to be the same size
as the start/end icons, ie the distance covered by 10 display pixels.
v.net.path uses a default of 1000 map units, but perhaps the 10 pixel
way is better as it will give a reasonable default for lat/lon locations.
?
If I don't get to this in TclTk, these updates will make it doable in
wxPython too.
