Claim 13:
14. A non-transitory computer readable medium including instructions that when executed by a processor are configured to perform:
receiving point cloud data associated with multiple locations in a geographic region as a vehicle travels along a path;
calculating a sign position candidate for the point cloud data;
receiving image data associated with the geographic region;
calculating a sighting frustum from the image data;

calculating a parsimony value for the intersection of the sighting frustum to the sign position candidate to remove one or more association sets of the plurality of association sets; and
storing a sign location in a geographic database in response to the coverage value and the parsimony value.
