Method of updating map

According to other preferred embodiments, the management server comprises a data transmitting unit for suitably transmitting the data with the user terminal through the wireless communication network; a layer management unit for suitably managing the information about the map data version, and for suitably dividing the map data into a plurality of layer units on the basis of an area unit as well as the data attribute and the data type, wherein, after comparing the map data version received from the user terminal with the latest map data version of the management server, the layer management unit produces information about the modified update area, the layer list and the data capacity, and suitably transmits the update data which are requested from the user terminal; and a map DB for storing the map data corresponding to the version information and the map data which are divided into the layer units.

fuels derived from resources other than petroleum).

As referred to herein, a hybrid vehicle is a vehicle that has two or more sources of power, for example both gasoline-powered and electric-powered.

According to other further embodiments of the present invention, each of the objects for constituting a map may preferably be composed of a lot of layers having suitable connectivity with adjacent areas such as road data according to a data attribute and a data type, and then, by deciding that updated parts are suitably included in a certain layer when an update of data occurs, it is possible to update only layers to be required.

It is understood that the term “vehicle” or “vehicular” or other similar term as used herein is inclusive of motor vehicles in general such as passenger automobiles including sports utility vehicles (SUV), buses, trucks, various commercial vehicles, watercraft including a variety of boats and ships, aircraft, and the like, and includes hybrid vehicles, electric vehicles, plug-in hybrid electric vehicles, hydrogen-powered vehicles and other alternative fuel vehicles (e.g.

The above features and advantages of the present invention will be apparent from or are set forth in more detail in the accompanying drawings, which are incorporated in and form a part of this specification, and the following Detailed Description, which together serve to explain by way of example the principles of the present invention.

The above and other features of the present invention will now be described in detail with reference to certain exemplary embodiments thereof illustrated by the accompanying drawings which are given hereinafter by way of illustration only, and thus are not limitative of the present invention, and wherein: It should be understood that the appended drawings are not necessarily to scale, presenting a somewhat simplified representation of various preferred features illustrative of the basic principles of the invention.

The present invention features a navigation system for partly updating a map layer, and a method for the same, in which, by dividing a map into locally small data areas considering connectivity with adjacent areas, and updating only areas updated among the divided areas, the navigation system is able to minimize a size of the updated data, and delete unnecessary procedures for post-processing in a user terminal. In a navigation system, a navigation terminal generally stores map data, and visually guides the optimum route to a destination using the stored map data.

30, 2009, the entire contents of which are incorporated herein for all purposes by this reference. Field of the Invention The present invention relates, generally, to a navigation system, and more particularly to a navigation system for partially updating a map layer, and a method for the same, in which the navigation system may divide a map into locally small data areas, wherein the navigation system may update only certain updated areas among the divided areas. Description of Prior Art In general, a navigation system is suitably equipped to a type of moving object, such as a ship, an aircraft, a vehicle, and the like, so that the navigation system may provide the driver with information as to the current location of the moving object, calculate an optimum route to a desired destination, and guide the driver on the basis of the route.

However, the real roads, buildings, facilities, or the like, may be frequently changed.

Accordingly, the map data of the navigation terminal may need to be frequently updated in order to express real roads, buildings, facilities, or the like.

The specific design features of the present invention as disclosed herein, including, for example, specific dimensions, orientations, locations, and shapes will be determined in part by the particular intended application and use environment.
