Mining oriented abnormal data based GIS

The present invention discloses a method of mining for abnormal data base of geographic information, geographic information according to the present invention attributes house number, road data according to road data and non-mining are abnormal data, wherein road data comprises abnormal data and distance data density anomaly, non-road abnormal data mainly from the abnormal data. Road distance to the abnormal data points to a road curve fitting to determine the distance, the density characteristics of abnormal data is not data of the same attribute within a certain range thereof; abnormal data is non-road as a reference point the center of gravity, the center of gravity calculated for each point distance determination whether the data is abnormal. The method of the present invention enables efficient mass data, the abnormal data mining function automatically.
