Claim 9:
10. A non-transitory, computer-readable medium comprising instructions executable by at least one processor to perform a method, the method comprising:
determining a first polygon that encloses roads of first data from a first source;
determining a second polygon that encloses roads of second data from a second source, wherein the first and second data cover at least a portion of a same spatial region, wherein the first and second data comprise aerial or satellite images converted to a vectorized list of the roads, and wherein the first and second polygons are of different sizes;
determining a polygon that simultaneously encloses both of the first and second polygons;
dividing the larger polygon into a plurality of tiles, each belonging to a different portion;
overlaying each of the first plurality of tiles over a corresponding portion of each of the first polygon and the second polygon;
comparing a first set of features extracted from each of the portions of the first data with a second set of features extracted from the corresponding portion of the second data;
computing, for each of the comparisons, a disagreement level;
selecting a second set of tiles from the first plurality of tiles based on at least one of the computed disagreement levels that satisfies a criterion;
displaying, to a user in one of the selected tiles being overlaid and according to a prioritization order according to the disagreement levels, features of a respective portion of the first data and features of a respective portion of the second data.
