I am trying to create a buffer around buildings to create a 'green wall'. First, I dissolved all buildings in order to create a buffer only around the buildings (flat roofs). However, after creating a buffer of 0.3m there is only 1 ID number.
I would like to create different ID numbers for every building block, because I need to perform an analysis for the different buildings. I can't do it manually, because there are too many of them.
- buffer around every building block (flat roof)
- different ID numbers
Does someone have a solution to my problem?
I am working with QGIS 3.24.2.
