Methods for validating track databases based on the contents of a geological database. The track database stores a piecewise-polynomial spline as a geometric representation of the track, along with offsets from spline points to represent the geo-locations of features on the track. After the computations associated with the geometric representation are completed and the track database is populated, the geo-locations of features in the track database are checked for consistency with the geo-locations of monuments in the geological database. If the geo-location of a feature in the track database is found to differ by more than a threshold distance from its projected geo-location, as computed from offsets from a monument in the geological database, then corrective action is taken. The illustrative embodiment also enables the validation of data values in the track database and relationships among track features. |
