Abstract: 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.

Abstract: 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.
