Hi list,
I have some (basic) vector related questions:
After cleaning a vector map, it doesnt have continuous (i.e. no gaps in
numbering) categories, how do I efficiently reset these to so that they
have regular increments (i.e. 1) again? r.clump does something very
similar with vectors. I have tried dropping and adding a new table,
deleting and adding categories with v.category. I thought v.reclass may
do the trick but I'd first need a column with continuous numbers for that.
Somewhat related to this, what is the best/most efficient way of
updating an entire column of a vector table from a numpy array. v.update
does do it for one entry only, i.e. looping would be possible, but that
takes ages. Would I have to go back to using basic sqlite3 packages for
that?
Thanks,
