Techniques described herein may be used to identify anomalies in a joined region of two datasets. For example, a computer system may determine an elevation anomaly data point in based on an elevation criterion. The computer system may determine a set of buffer points surrounding the elevation anomaly data points. The computer system may user the set of buffer points to reduce the number of data points for adjusting. The computer system may determine a reduction factor based on the buffer points. The computer system may then apply the reduction factor to points in the buffer points and other points.

Map data adjustments for anomaly correction

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.

Polygon block shrinkage using push vectors

Techniques described herein may be used to using a medial axis of an overlap or gap to assign portions of the gap or overlap to adjacent polygons. For example, a computer system may identify a subject polygon defined by a first polygon and a second polygon. The computer system may determine a plurality of line segments within the subject polygon and that define a medial axis of the subject polygon. The computer system may assign a first face of the plurality of faces to the first polygon. The computer system may update a first boundary of the first polygon to include a first face area corresponding to the first face. The computer system may cause rendering, on a display, of a map view that includes the updated first boundary.
