[GRASS-user] v.patch fix/workaround needed

[peter.loewe at gmx.de]

Hi,

I am using GRASS6.3 (on SuSE) to create a polygon layer out of several individual polygons.

In a first step, a polygon ("A") is created using v.patch from an outline and a centroid. This works fine.

In a second step, the newly created polygon is added to a larger set of polygons ("SET") using v.patch again.

In a few cases (reproducable) the "SET" polygon is NOT extended by the proper polygon "A" but the centroid of "A" and the polyline of "A" (the process works correctly in 9 out of 10 cases).

Since this process is to run as a script, how can the disjoint tuple of controid-A and polyline-A in the "SET" vector layer be mended again ?
