I'm a beginner and I usually use Qgis. I would build a map made by a pie chart pattern, as in the picture attached. The pie chart returns the values in percentage of the land use soil. I would like that the system shows the percentage of the land use coverage in each quadrant of the grid. E.g. Square XXX 10% urban, 21% forests etc. for each quadrant.
I decided to do it this way: 1 - I build a grid of squares; 2 - Intersect squares with the use of the soil; 3 - ????
As output result I obtain a shape that is the intersection between the grid of the squares and the geometries of the land use soil. I don't know how go ahead working. I need to figure out how to reassemble the square keeping the land-use values.
