Mask out branches and connect data to get spatial

Hey, I am working on a studyproject about swamps and i try to bring Gis-Data into a more spatial situation. I made it already to seperate different use of land but still try to bring data together
How do i mask out only the branches of agricultural use in my hight of biomass ? What component do i need to reconnect the use value and the hight value to bring it in the right location ? Do i have to keep the branchnumber as an identity to reconnect it with the correct data ? So for example branch {0;1} it want to lift the surface of agriculture to 42.709 cm. (103.5 KB)
