[GRASS-user] Copy and concatenate a vector attribute between layers

[Peter Tittmann]

Hi,

I have a vector (`POINT`) which has two layers containing relevant attributes (’strata’ and ’stand’). I would like to concatenate the two values into a new attribute for Layer 1 (’<STRATA>_<STAND>’). I’ve been struggling to sort this out for too long and am tapping out. Its probably blatantly obvious but it has escaped me.

Thank you!

Here are some specifics.
