Replying to mlennert:

Replying to marisn: This is logicial in the sens that only the centroid has a cat=5109. No boundary has this cat. So this would mean implementing a specific algorithm to check which boundary needs to be exported together with this centroid.

Basically it could be possible. Currently v.out.ascii opens vector map on level 1 (without topology). This would require level 2 (topology). I can imagine special flag which writes out also areas (boundaries and centroids), not only centroids. The problem is that boundaries of adjacent areas will printed twice. I am not sure whether it's a good idea to extend functionality of this module in this direction. Any opinion?

    initial v3  
    11It's not possible to export areas selected by SQL WHERE clause.
    22Example from NC data set. Let's export only lake with CAT=5109:
    3 {{{
     3{{{ood
    44v.out.ascii input=lakes@PERMANENT layer=1 output=vbuffer_fail_on_area3 where=cat=5109 format=standard
