Geographic information data fusion system

The invention discloses a geographic information data fusion system which comprises a geographic information data interface unit, an information exchange platform unit and an information application front-end processor unit. The geographic information data interface unit is used for classifying and storing input geographic information data according to a geographic information data classification table. The information exchange platform unit is used for reading the geographic information data in the geographic information data interface unit according to a preset refresh cycle, converting the geographic information data into geographic information data in a preset format and outputting the geographic information data. The information application front-end processor unit is used for extracting personal information contained in the geographic information data output by the information exchange platform unit, obtaining activity track information corresponding to the personal information from the geographic information data output from the information exchange platform unit, setting access permissions of the personal information, creating fusion geographic information data containing the access permissions and the personal activity track information, setting personal information identifiers for the fusion geographic information data and storing the fusion geographic information data with the set personal information identifiers. By means of the geographic information data fusion system, data fusion sharing application can be achieved.
