I am working with QGIS 3.24.2. In the image you can see red buildings (representing a green roof) and the green polygons are gardens.

Every green building has a value to reduce noise pollution in the garden. In the end I need to have a summed up noise reduction value for every garden that touches a building.

I need:

  • green roofs that are linked to a garden
  • noise reduction values of every green roof assigned to the garden (summed up) enter image description here

Is there an easy tool available which makes this analysis possible?
