1. A computer-implemented method, comprising:
determining, in accordance with an elevation criterion, an elevation anomaly data point in a joined region defined by a first elevation dataset and a second elevation dataset;
determining, in accordance with a buffer criterion, a set of buffer points surrounding the elevation anomaly data point, the set of buffer points comprising a set of elevation anomaly points in the joined region and comprising the elevation anomaly data point and at least one other elevation anomaly data point;
determining interpoint distances between buffer points in the set of buffer points;
determining, for at least one buffer point of the set of buffer points, a reduction factor based on a first interpoint distance for the at least one buffer point and a first elevation value of the at least one buffer point;
applying the reduction factor to the at least one buffer point to adjust the first elevation value; and
causing rendering, on a display, of a map view that includes the at least one buffer point with the adjusted first elevation value.
