In QGIS I am working on a streets layer, on the attribute table I have these fields:
"CVE_VIAL"
is an ID of the street and each street could be divided into several sections, each of these sections have an ID ("ID_TRAMO"
) that when concatenated with "CVE_VIAL"
results in unique "ID"
.
In this example, I've already calculated one by one "ID_TRAMO"
with consecutive numbers, and what I'm trying to find right now is a way to do this automatically.
