Abstract:
A method for automatically creating points of interest by identifying geographic information on a screen of a portable navigation device. A first geographic information is retrieved from an information page shown in the screen of the portable navigation device and recognized by comparing with the first geographic information with a geographic information of landmarks stored in a map database of the portable navigation device. It is determined whether the first geographic information is in the map database. If the geographic information is in the map database, a first GPS coordinate corresponding to the first geographic information is obtained and stored as a first POI.
