1. A machine-implemented method for determining a true geometry of a point of interest (POI), the method comprising: identifying, using one or more computing devices, a plurality of geometries associated with one or more points of interest according to one or more relationships; generating, using one or more computing devices, a candidate set of geometries for a first point of interest of the one or more points of interest, the candidate set of geometries including at least two candidate geometries that include geometries being associated with the first point of interest according to the one or more relationships; ranking, using one or more computing devices, the candidate geometries of the candidate set according to a ranking criteria, wherein the ranking sorts the candidate geometries according to the likelihood of the respective candidate geometry to be a true geometry of the first point of interest; selecting, using one or more computing devices, a first candidate geometry of the candidate geometries of the candidate set as the true geometry for the first point of interest according to the ranking; and storing, using one or more computing devices, the first candidate geometry in association with the first point of interest.
10. The method of claim 1 , wherein the one or more relationships are one of an occupies or is contained by relationship and wherein a candidate geometry is more likely to be the true geometry of the first point of interest if it is associated with the first point of interest according to an occupies relationship.
