Hi Markus, Thanks for reply. I am making intro more detailed. I checked wxpython for the technologies I suggested. It seems wxpython might support it, though I am having a detailed look at it. Sudeep On Sun, Apr 8, 2012 at 12:29 AM, Markus Neteler wrote: > On Thu, Apr 5, 2012 at 9:53 PM, Sudee

The one-cell areas are correct, at least within the logic of vector topology. If you used r.to.vect with the -v flag, the one-cell areas will have the same category like the neighboring areas belonging to the same basin, that is, area calculations for basins done with v.to.db will be correct and al

[GRASS-dev] removing small multiple polygons created by r.stream.basin + r.to.vect

2012-04-09 Thread Margherita Di Leo
Hi, when I delineate a basin using r.stream.basins, and convert the raster map of the basin into vector (r.to.vect), I sometimes get multiple polygons: i.e. one bigger and a couple of one cell polygons. (you can reproduce the behavior in NC sample dataset using easting=643677.87 northing=222800.24
