Abstract: Disclosed is a seamless complex positioning method using heterogeneous positioning techniques, the method including: performing, by a positioning control apparatus, satellite signal-based positioning in an area where a satellite signal is received; determining, by the apparatus, whether a first position of a mobile terminal determined using satellite signal-based positioning is close to a shaded area; determining, by the apparatus, a non-satellite signal-based positioning scheme supported in the shaded area when the first position is close to the shaded area; determining, by the apparatus, a second position of the mobile terminal while performing satellite signal-based positioning and positioning according to the non-satellite signal-based positioning scheme simultaneously when the first position is close to the shaded area; and stopping, by the apparatus, satellite signal-based positioning and performing only positioning according to the non-satellite signal-based positioning scheme when the second position is inside the shaded area.

Abstract: A system for dynamically visualizing POI (Point Of Interest) attribute information includes a POI attribute database unit that stores POIs and attribute information of the POIs; and a POI condition searching unit configured to search the POI attribute database unit for attribute information of POIs depending on several conditions to produce the searched POIs. Further, the system includes a service providing unit configured to perform a services such as a web map service or a navigation service using the searched POIs provided from the POI condition searching unit; and a display unit configured to display results of the service.

Abstract: A vehicle detecting apparatus obtains a magnetic signal from strength of a geomagnetic field generated due to a movement of a vehicle, and detects and classifies the moving vehicle on the basis of information regarding the latest magnetic signal change pattern indicating a change in the magnetic signal and information regarding a magnetic signal change pattern with respect to each vehicle stored in a database. The vehicle detecting apparatus receives detection and classification information regarding a vehicle which has actually moved, from an external information providing server, and gradually updates it through learning of a magnetic signal change pattern of the corresponding vehicle.
