Abstract: Provided are a method for attaching a geographical tag to digital data and a method for providing geographical name information for geotagging. When a digital device periodically provides its position information, the server creates a position database. When the digital device requests geographical name information associated with the digital data, the server estimates the position of the digital device at a time when the digital data was created and transmits geographical name information corresponding to the estimated position to the digital device. The digital device attaches the geographical name information to the digital data.
