[GRASS-user] How to remove surplus centroids sitting right on a boundary line ?

[Peter Löwe]

Hi all,

I have a vector layer (source: ESRI shape) consisting of areas and many surplus 
centroids, which need to be removed.
The surplus centroids are sitting right on the boundary lines of the areas: So 
each area has one proper centroid in its center, but also multiple fringe 
centroids sitting on its boundary line.

Which combo of v.clean tools (or other means) can handle the removal of the 
unwanted centroids ?

Hi Peter,

tool=string[,string,...]
...
rmdac: remove duplicate area centroids ('type' option ignored)

Did you try this and it fails?
