Hopefully a quick question that I'm struggling with. (I'm a long-time GIS user but trying to move my work to GRASS and other FOSS4G.) I'm using GRASS 6.4 RC6 on Windows XP.
I have a raster grid representing elevation at 2meter resolution. I have a line shapefile representing roads (about 20 roads total). I would like to get ASCII text files of x,y,z at about 1 or 2 meter intervals along each road. Any ides of what I can try? I thought v.drape might work. This converts my 2D road shapefile to 3D, but I'm not sure where to go from there. And this doesn't help getting 1 or 2 meter intervals. I also tried r.profile but this requires input as a listing of x,y coordinates, not shapefiles. I know there's a step here I'm missing. - John ************************************************** John Callahan, Geographic Information Scientist Delaware Geological Survey, University of Delaware URL: http://www.dgs.udel.edu **************************************************
