[GRASS-user] v.edit: unexpected behavior

GRASS GRASS user
1

   The attached PNG image shows catchment boundaries and data collection
points. I'm trying to delete those catchments with no contained points, but
v.edit is not working as expected.

   The topmost (northern) catchment with a data collection point has ID=4;
the catchment immediately to its west has ID=5. Using this syntax,

   v.edit map=catchments tool=delete id=5

I expected the entire catchment to disappear. It does not. Instead, the
common boundary between it and catchment id 4 is dissolved and the combined
catchment area designated ID=4.

   What have I done incorrectly?

From the manual :

cats - using category numbers

in your cmd you're using 'id'?

Helmut,

   Yes, because when I use the GUI to identify polygons the pop-up table
shows the numbers as IDs, not cats.

Thanks,

Rich

Have you tried it with cats instead of ids?

Helmut,

   Yes, and it certainly makes a big difference. :slight_smile:

Many thanks again,
