2 is a block diagram illustrating a logical configuration of a portable electronic map apparatus according to an exemplary embodiment of the present invention. As shown in FIG. 2, the portable electronic map apparatus according to the present invention includes an interface unit 200, an electronic map storage area 220, an execution program storage area 230, a user storage area 240, and a recovery area 250. ) May be included.

The portable electronic map apparatus 100 according to the present invention may be implemented using various portable data storage devices such as a USB memory, a portable HDD, a RAM drive, and the like, and will be described below with reference to an embodiment implemented using a USB memory. do.

The interface unit 200 is connected to an external terminal 110 such as a personal computer to perform data input / output. As described above, when the portable electronic map apparatus 100 according to the present invention is implemented using a USB memory, the interface unit 200 adopts a USB interface. If another portable data storage device is adopted, an interface unit according to the interface standard of the device will be provided, and according to the present invention, a near field wireless communication unit using near infrared communication or RF communication may be adopted as an interface unit.

The memory 210 in which data of the portable electronic map apparatus 100 is stored is divided into an electronic map storage area 220, an execution program storage area 230, a user storage area 240, and a recovery area 250.

The electronic map storage area 220 stores electronic map data for constructing the electronic map according to the present invention. More preferably, the electronic map data according to the present invention is configured to generate an electronic map by mixing vector data and scalar data for more efficient electronic map generation / display, according to a predetermined type of data. Each data constituting the electronic map is stored in a vector format or a scalar format.

A vector file is an image composed of lines and curves defined by mathematical objects. Unlike bitmap images, vector images automatically resize at any resolution, so you get a clear image regardless of the resolution. In other words, vector graphics can be optimized to meet the resolution limitations of output devices such as printers and monitors. Therefore, the quality of graphics printed on 600 dpi printers is better than that of 300 dpi printers. You can get a good output. Since the file size is determined by the number of points and lines, a simple image has a much smaller capacity than a bitmap file of the same size, but there is a limitation in expressing natural images and colors. The vector method is a method supported by Illustrator, Freehand, CorelDraw, and so on, and consists of objects made of paths. Therefore, it is useful for letters, logos, lettering, patterns, symbols, marks, characters, programming, cartoons, illustrations, and graphs. Because the vector method is composed of Bezier curves, a mathematical function that connects a point to a point, unlike a bitmap image, it is not damaged even if the object is reduced, enlarged or distorted. Therefore, the concept of resolution does not exist. However, the resolution may be determined at the time of output. Each object in a vector graphic has independent properties, so you can move or change the property over and over without losing affect to other objects in the entire graphic, while maintaining the original shape. Graphic work and 3D modeling graphics, which require a design process to create and systematically edit each object, are based on vector graphics suitable for these characteristics. Therefore, in order to make the most of the characteristics of the vector image, the present invention configures the user-generated data and the city-county boundary data among the data constituting the electronic map as vector data.

On the other hand, the bitmap method is a method of creating a single image by gathering pixels, and is a method of Photoshop, paint shop painter, etc., which specializes in compositing, effecting, distorting, transforming, color correcting, and correcting photographs or images. can do. However, being made of pixels also means that the image will be damaged if the image is reduced or enlarged. This is because a change in the size and shape of a bitmap image is not a change in the size of the pixel itself, but a change in the number of pixels. Therefore, if the image is reduced, the number of pixels is reduced and the original information is damaged, resulting in an image distortion. Magnifying an image is like stretching the pixels of an image with a small number of pixels, which results in a mosaic phenomenon without the original delicacy. The bitmap format is a way for small squares, called pixels, to gather together in color to create an image. Therefore, if you look at the magnification, you can see the shape of the pixel and see the broken phenomenon. It is possible to express naturally and realistically, but you need to increase the resolution in order to create a high-quality image. have. Bitmaps are an image structure consisting of 'pixels'. 'Pixels' act as dots that represent an image on a computer's screen. If a picture you draw is read through a scanner, the picture is digitized into a number of pixels and becomes a bitmap image. The word pixel is a compound word of two words: picture and element. Therefore, in order to maximize the characteristics of the scalar method, in the present invention, 'scale (map data for each scale)' of the data constituting the electronic map is composed of scalar (bitmap) data.

More preferably, the above-described electronic map data may be divided into predetermined regional units (regional units or tile units) and structured and stored in a file indexing method. In the case of using the file indexing method, first, only the image angle of the required portion is read out to output the electronic map screen area (the area where the map is displayed), and secondly, when updating the electronic map data, It is possible to update the area / tile unit that needs to be updated without updating the map data, so that it is possible to update more quickly. Third, the general combination is difficult by dividing the file into angles in a specific order. .

The user storage area 240 stores personal data of the user. At this time, the stored personal data of the user may also store personal data irrelevant to the electronic map according to the present invention, and real estate related information (for sale information, seller information, brokerage) input by the user in the process of using the electronic map according to the present invention. Form information, etc.) may be stored. In this manner, since the information input by the user while using the electronic map is stored in the user storage area 240, the user is connected to the type of the external terminal 110 connected using the portable electronic map apparatus 100 according to the present invention. There is an advantage that you can always use the information you have stored.

In the execution program storage area 230, an execution program for generating / displaying an electronic map and real estate related information according to the present invention using the external terminal 110 is stored. In this case, as described above, when the execution program according to the present invention is configured to be driven independently, the execution program is stored to be driven independently, and when installed and driven on the external terminal 110, an installation copy of the execution program Will be saved.

In addition, the portable electronic map apparatus 100 according to the present invention may further include a recovery area in which the recovery program 252 is stored so that the electronic map data or the execution program is damaged. In the process of using the program, data may be damaged by virus, malware infection, etc., or data may be damaged due to user's carelessness. The recovery area 250 according to the present invention can not be erased and written by the user arbitrarily, and is impossible to access by a virus or other external device. The recovery area 250 stores the minimum recovery program 252 necessary for the recovery of the electronic map data and the execution program. At this time, the recovery program 252 may be configured to store a kind of automatic installation, or to access the electronic map service server 130 via the network 120 receives the data transmitted and receive the electronic map data or the execution program It can also consist of a recoverable program.
