Hi Anne,
One way to go around the problem is to digitize the center points of each
circle; convert these to a raster file; run r.buffer on the raster at high
resolution; reclass the map to 1 catagory; run r.poly on the reclass map to
get a vector map of irrigation circles.
Good luck,
rono
We are digitizing field boundaries from an aerial photography. A centre pivot
irrigation system had been used on some fields and we need to digitize circles.
Any suggestions on how to digitize circles? I did read in an earlier message
about v.circle. Can somebody tell me where we could locate a copy of v.circle
and how to use it?Thanks
