I need to create one map atlas for each municipal administration filtering the coverage layer (red rectangles = map sheets) by municipal administrations boundaries layer (green polygons). How is it possible to solve this problem?
First in atlas use the municipality green polygon by some name or code, then in the properties from red polygons use symbology by rules, and in the expression use
intersection(@geometry,@atlas_geometry), with this solutions I did something similar, my result was the municipality green, and the red polygons
I hope can help
