Dear list
I break a number of features in a vector map into two pieces using v.edit, tool=break and specific coordinates. This results in two parts with identical attributes after breaking (which is what I want) but also the cat is identical.
I think, this is the reason why I get exactly the same length for the two parts when calculating it using v.to.db, tool=length. Likewise, the end coordinates cannot be computed as there is more than one element for some categories.
How can I update the category to unique values for each feature?
Thanks for any suggestions,
Mira
