Method of for generating and searching through trajectory content performed in navigation device

A method of generating trajectory content in a navigation device, the method comprising:

• extracting trajectory data based on information about a start point and an arrival point and information about parcels and links between the start point and the arrival point, and recording the extracted trajectory data on a specific file;
• registering position information about multimedia data stored in a local directory in the specific file;
• and
• mapping the trajectory data and the multimedia data together.

A navigation device, comprising:

• a user interface unit that establishes a map region;
• a display unit that displays trajectory data and multimedia data;
• a map database unit that stores map data and trajectory content data;
• and
• a controller that compares information about first parcels in a map region established by the user interface unit with information about second parcels including information about links of specific trajectory content, determines whether information about the specific trajectory content is included in the map region, and displays the determined information about the trajectory content on the display unit.

A computer readable recording medium storing a program that, when executed by a computer, performs a method comprising:

• establishing a predetermined search region from a current position;
• extracting information about first parcels included in the established search region and information about second parcels including information about links of specific trajectory content;
• and
• determining whether the specific trajectory content is included in the established search region by comparing the information about the first parcels with the information about the second parcels.
