I'm a Norwegian student currently conducting a series of site analyzes for a city. In that context I wish to create a building density map but struggle a bit to find out how.
I have made a fishnet polygon of 50x50 meter and wish to find out how much built area there is in each of these squares. My goal is to color the squares according to how much percent of the squares are built area. Both the fishnet and the buildings are polygons and are editable. Please see the image.
Can anyone help me perform the analysis?
