[GRASS-user] Panning with r.profile or the gis.m profiler

You can pan the display, but not at the same time you are trying to draw a
profile line.
  
So then the best that can be done is to run multiple transects with r.profile while outputting a file with co-ordinates, then stitch them together and calculate the chainage from the co-ordinates? I suppose calculating the chainage from the co-ordinates is easier than trying to ensure the end point of one transect coincides with the start point of the next.

PS. I'm doing some long-sections for a pipe network.

Sorry for being ignorant, but why You don't use plain r.profile to
generate profile values that can be feed into any graph plotting
application?
Use d.where or gis.m identification tool to gather all turning points
along pipeline and then feed resulting list into r.profile. Save
r.profile output to some text file and then do some GNUPlot

Thanks Maris

Yes a sequence of d.where runs piped into a file and appended each time would work to build the input for r.profile. I didn't think of that - thanks for enlightening me :slight_smile:

hi,

some weeks ago Andrea Ricci post a solution to export a profile in
.dxf format that can be useful.

i released that i answered out of the list, i will post it again.

i would like to use grass for a similar propose, power line, but i
have been unable to use it, so if you where able to use it, it would
be kind if you tell us how you managed.

best regards
