Patent ID: 8307013

Claim:
A method for geotagging a digital data, the method comprising the steps of: providing, at a set interval of time, geographic position information of a digital device to a server by the digital device so that the server creates a position database based on the geographic position information wherein the position database includes the geographic position information and a time at which the digital device transmits the geographic position information; creating digital data by the digital device; requesting the server to provide geographical name information associated with the digital data based on the geographic position information of the digital device; receiving the geographical name information from the server; and associating the geographical name information to the digital data, wherein the geographic position information and a time at which the digital device provides the geographic position information to the server are recorded in the position database, wherein, in case the time at which the digital device provides the geographic position information to the server is different from a time at which the digital device requests the server to provide the geographical name information associated with the digital data, a position of the digital device at a time t m is determined by a function of f(t k ) and f(t k+1 ) in which t k and t k+1 denote times at which the digital device provides the geographic information, the times t k and t k+1 being adjacent to the time t m at which the digital device requests the server to provide the geographical name information, and f(t k ) and f(t k+1 ) denote positions of the digital device at the times t k and t k+1 , respectively, wherein the position of the digital device at the time t m is determined by interpolation using f(t k ) and f(t k+1 ).
