Abstract

The present invention discloses a navigation system and the method used for searching point area of interest. The navigation system comprises a storing module which is stored with interest point information and an interest point searching module. The interest point information comprises interest point data, area index and classified index. The area index and classified index are related with the interest point data respectively according to the area and classified property of different interest point data. The interest point searching module comprises an area searching sub-module and a classifying searching sub-module which are connected with the storing module through information connection. The area searching sub-module and classifying searching sub-module respectively receive the area information and classifying information input by the user for searching the area index and classified index in the storing module and selecting the corresponding interest point data for outputting. Asthe area index and classified index related with the interest point data are set according to the invention, the screening can be further executed according to the classified information on the base of executing area searching. The interest point data unnecessary for the user is screened out and the searching result is more accurate.

Description

technical field [0001] The invention relates to the field of GPS navigation, and more specifically, relates to a navigation system and a method for area retrieval of points of interest in an electronic map used by the navigation system. Background technique [0002] At present, the global positioning system (Global Positioning System, GPS) for vehicles is one of the important application directions of GPS navigation. The GPS antenna of the car GPS navigation system receives the data information transmitted by at least 3 of the 24 GPS satellites around the earth, combined with the electronic map stored in the car navigation terminal, the position coordinates determined by the GPS satellite signal and this match to determine the exact position of the navigation object in the electronic map. [0003] figure 1 Shows the structural composition of the existing navigation system: [0004] Described navigation system comprises: loudspeaker 1, memory module 2, input device 3, soun...
