It relates to a real-time update method for walking map data.

In general, a navigation system is mounted on various moving objects such as ships, aircrafts, vehicles, etc., and informs the driver of the current position of the moving object, calculates an optimal route to a desired destination, and guides the driver according to the route.

Recently, a navigation system using GPS has become common, and such a navigation system receives geographic information that numerically displays information about a feature such as a real road, a building, a facility, etc. from a information center through a mobile terminal, Using the data stored in a storage medium such as a CD ROM, the user can visually guide the optimal route from the current location to the destination. For example, when the navigation system moves, the location information received in real time through the GPS receiver is matched with the geospatial data secured in advance, thereby guiding the optimum path to the destination for the moving object through the screen.

However, features such as roads, buildings, and facilities may change from time to time. Accordingly, the geographic information data stored and used in the user's navigation system also needs to be updated at any time to reflect the changed feature information.

Hereinafter, a method for updating geospatial data according to the prior art will be described with reference to FIGS. 1 and 2.

And a geospatial data data providing server 40 which provides updated geospatial data to 10.

As shown in FIG. 2, the geographic information data providing server 40 converts map information into data, divides and stores a map for a specific region into N cells, and designates a street address for each divided cell. If the file size of the divided cells exceeds the size that can be transmitted through the wireless network 30, the cells are segmented, and the cells are further examined and segmented if the size is large. ) To a size that can be transmitted. As described above, the geospatial data providing server 40 dividing the entire geospatial data area 44 into cell units and storing the geospatial data, when the geospatial data of a portion of the geospatial data is updated, includes the updated data.

As described above, the conventional method for updating geographic information data receives all data of the cell area 2 including updated data from the geographic data data providing server 40 through the mobile terminal 10 provided in the navigation. All data in the cell area 2 including the updated data is updated in the corresponding cell area of the entire geospatial data area 44 previously stored. However, such a method of updating the geospatial data requires a large amount of data to be downloaded because the mobile terminal 10 downloads and updates all the data in the updated cell area 2, so that the user of the navigation system has a high wireless network fee. There is a problem that must be paid.

Furthermore, the update information provided by the geographic information data providing server 40 may not be the latest information. This is because the surrounding environment is changing day by day, and buildings and facilities (for example, intersections, traffic signal networks, crosswalks, etc.) are often disappeared or newly established, and accordingly, the geographic information on vehicles is required to be updated frequently. This is because real-time updating of geographic information is very difficult because it is a task that requires a lot of human and material resources.

In addition, the existing geospatial data is concentrated on the map data for the vehicle, so that it is not possible to provide proper road guidance to those who walk on foot without using the vehicle, and proper data has not been updated.
