Hi List,<br>
<br>
This is probably more due to my lack of understanding of how v.edit<br>
works. But here it goes.<br>
<br>
I have a polygon vector layer where some of the polygons have a 'No<br>
data' label. I'd like to delete those polygons so I ran the command,<br>
with the following output:<br>
<br>
v.edit map=teste@isna tool=delete where="label like '%no data%'"<br>
Selecting features...<br>
207 of 7200 features selected from vector map <teste@isna><br>
207 features deleted<br>
Building topology for vector map <teste@isna>...<br>
Registering primitives...<br>
6993 primitives registered<br>
29546 vertices registered<br>
Building areas...<br>
2195 areas built<br>
264 isles built<br>
Attaching islands...<br>
Attaching centroids...<br>
Number of nodes: 3086<br>
Number of primitives: 6993<br>
Number of points: 0<br>
Number of lines: 0<br>
Number of boundaries: 5017<br>
Number of centroids: 1976<br>
Number of areas: 2195<br>
Number of isles: 264<br>
v.edit complete.<br>
<br>
After that, the offending polygons where deleted however, their<br>
boundaries are still present. That is, when I load the vector in the map<br>
display, I still see the boundaries in some polygons, even though the<br>
area is not filled. Is this the intended behavior? I tried using the<br>
areadel tool but then the whong polygon was deleted. I'm guessing the<br>
shared boundary of a valid polygon was removed and his caused problems.<br>
<br>
Attached is a sample of what I'm seeing after v.edit delete<br>

Attributes of areas are linked to the centroid of the area. So the features you select through your query are these centroids, not the boundaries.<br>
<br>
It would probably be nice to have a type=area option in v.edit.<br>
<br>
To get the same result, you could use v.extract -r type=area.<span class="HOEnZb"><font color="#888888"><br>
