US Patent 11988524 Polygon block shrinkage using push vectors

Techniques described herein may be used to adjust sets of bounded polygons in a predictable and automated manner. For example, a computer system may access a first set of polygons of a first type and a set of polylines of a second type. The computer system may group polygons from the first set of polygons into face groups. The computer system may determine that a first face group is anomalous based on a perimeter of the first polygon and first property of a first polyline of the set of polylines. The computer system may, for the first face group, compute a set of push vectors and apply the set of push vectors to the first face group.
