Dear list,
I try to delete features from a vector theme using v.edit.
After specifying the attribute column to choose with v.db.connect
This sentence is not clear: v.db.connect allows you to connect a map to
a table indicating the column of the table which contains the category
values of the vector features you are linking to. You cannot "specify a
column to chose".
I was entering the following:
v.edit [EMAIL PROTECTED] tool=catdel ids=Geb053362
There comes the message within the the output of v.edit:
Tool catdel requires option cats
Two issues:
- tool=catdel deletes only the category value, not the feature itself,
if you want to do the latter, use tool=delete
- ids= is not what you want to use (you have to know the internal ids of
vector features), but rather where=, so something like this:
v.edit [EMAIL PROTECTED] tool=delete
where="SelectColumn=='Geb053362'"
where SelectColumn is the column which contains your selection criteria.
