Abstract

Disclosed is a navigation service method using geographic information, comprising the steps of: storing geographic data in a database, the geographic data including network data for indicating geographic coordinates, calculating a route, and matching a GPS (Global Positioning System) code received from GPS satellites and the geographic coordinates, point data having position information for a search, and background data that is an aerial photograph or a satellite photograph; searching for a desired position or calculating a current position according to a GPS code in the case of receiving the GPS code from the GPS satellites; loading background data and map data about a predetermined area including the current position from the database; and generating map image data overlapping the loaded map data and background data and displaying the generated map image data to a display.

Claims

1. A navigation service method using geographic information, comprising the steps of:

storing geographic data in a database, the geographic data comprising network data indicating geographic coordinates, calculating a route, and matching a GPS (Global Positioning System) code received from GPS satellites and the geographic coordinates, point data having position information from a search, and background data that is an aerial photograph or a satellite photograph;

searching for a desired position or calculating a current position according to a GPS code in the case of receiving the GPS code from the GPS satellites;

loading background data and map data of a predetermined area including the current position from the database; and

generating map image data overlapping the loaded map data and background data and displaying the generated map image data to a display.

3. The method of claim 1, wherein:

the map data and background data are tiled in plurality and compressed, each compressed map data and background data assigned with an index, and

map data and background data corresponding to the predetermined area are searched by the index and the found compressed map data and background data are loaded and restored.

5. A computer readable record medium recording a program for implementing the method according to claim 1.

2. A navigation service method using geographic information, comprising the steps of:

storing geographic data in a database, the geographic data including map data for indicating geographic coordinates, calculating a route, and matching a GPS code received from GPS satellites and the geographic coordinates, background data that is an aerial photograph or a satellite photograph, and point data indicating a point of interest;

loading the point data from the database and detecting points of interest with respect to a plurality of positions on the route requested for search, in the case a request for searching a route is received via a user interface;

loading the map data from the database to detect a route connecting the points of interest, in the case the points of interest are detected;

loading point data, and map data and background data with respect to a predetermined area from the database, in the case the route is calculated; and

generating map image data overlapping the loaded map data and background data and graphic data for indicating the route and point data, and displaying the generated map image data to a display.

4. The method of claim 2, wherein:

the map data and background data are tiled in plurality and compressed, each compressed map data and background data assigned with an index, and

map data and background data corresponding to the predetermined area are searched by the index and the found compressed map data and background data are loaded and restored.

6. A navigation service terminal using geographic information, comprising:

a database storing geographic data including map data for indicating geographic coordinates, calculating a route and matching a GPS code received from GPS satellites and the geographic coordinates, and background data that is an aerial photograph or a satellite photograph;

a display displaying map image data;

a GPS receiver receiving a GPS code from GPS satellites;

a memory storing predetermined types of information; and

a controller receiving a GPS code from the GPS receiver to calculate a current position, loading map data and background data with respect to a predetermined area including the current position from the database, generating map image data overlapping the loaded map data and background data, and displaying the generated map image data to the display.

7. The terminal of claim 6, further comprising a user interface providing an interface with a user, wherein:

in the case a request for searching a route is received via the user interface, the controller loads the point data from the database to detect points of interest with respect to a plurality of positions on the route requested for search, loads the map data from the database to calculate a route connecting the points of interest, loads point data, and map data and background data with respect to a predetermined area including the route, generates map image data overlapping the loaded map data and background data, and graphic data for indicating point data and the route, and displaying the generated map image data to the display.

8. The terminal of claim 6, further comprising a wired/wireless network interface providing an interface with a wired/wireless network, wherein:

the controller accesses a navigation service server via the wired/wireless network interface, downloads updated geographic information, and updates geographic information of the database.

9. The terminal of claim 6, wherein any one of a topographical image and an illustrated map image is used as the background data.

10. The terminal of claim 6, wherein:

the map data and background data are tiled in plurality and compressed, each compressed map data and background data assigned with an index, and

the controller searches for map data and background data corresponding to the predetermined area by the index, and loads and restores the found compressed map data and background data.
