2. Description of the Related Art Geographical information having a map and main information related to it (for example, famous buildings, shops, images near intersections, etc.) is stored in a CD-ROM, and radio waves received from geostationary satellites and radio stations are used. Navigation devices that calculate the current position of the driver and the azimuth (direction of travel) of the driver and read the geographic information related to the current position from the CD-ROM based on these position information and display it on the display have become more and more popular recently. There is. On the display of the navigation device, a map including the driver, mainly in the forward direction, is displayed by the plane method or the perspective method.The marker that displays the current position, the shortest route to the destination, the horizon, the main image in the vicinity, etc. Any one or more of is displayed. For such a navigation system for automobiles, Japanese Patent Laid-Open No. 1-
Map information is stored in a CD-ROM with a hierarchical structure of two or more of fine data and rough data, such as 263688.
There is an example in which the periphery of the current position is finely enlarged and the distance is displayed small and coarse according to one of various perspective views according to the current position and azimuth information obtained from the current position detector using a space satellite or the like. Further, it has been proposed to superimpose a virtual image or an explanation screen associated with each coordinate point (Japanese Patent Application No. 7-160196). Such a navigation device for an automobile is a single unit incorporating a CD-ROM, and is basically configured as one closed information source,
Data is updated or added only to a very limited extent. For example, if you want more detailed and special information, you may purchase an upgraded CD-ROM or other recording medium (floppy disk, IC card, etc.) and replace it, or most recently, a PC (personal computer).
It has been proposed that the storage transfer device adds the additional information input and edited in step S1 to the storage device of the navigation device.

[0003]

As described above, the navigation systems currently in practical use are finally available from individual usage to combined usage of PCs and additional display of road-related information such as traffic congestion information. There is a growing number of linear and area-specific uses of. On the contrary,
Methods and devices that can effectively use information related to the landscape of the activity status of cities and areas (including emergency disasters) have not yet been developed. INDUSTRIAL APPLICABILITY The present invention relates to P for adding or processing information between navigation devices for automobiles or for information
Mutual exchange of information with C or transfer of information intervening between these (through a portable type such as an electronic notebook, or a wireless or wired transfer type such as a remote memory transfer device) Of course, comprehensively transfer the information centered on the landscape data obtained from the cameras installed at high places and stored in the center station and the local station (common station), and integrate the overall activities of the city and region. In this way, the challenge is to make multimedia, and in this way, the landscape obtained by the center station or local station is used in real time to grasp or monitor the environment (situation, disaster, etc.) of the city or region, and drive the car. For convenience, the judgment of the pedestrian (PDA) is improved. Further, it is difficult to interpret the scenery obtained by the center station or the local station as it is, and it is necessary for the urban environment monitor and the driver to easily interpret it. An object of the present invention is to solve this problem. In other words, there is a system in which a surveillance (video) camera is installed in a building, tower, or the like with a good view of the city and is remotely controlled. This surveillance camera shows the surrounding cityscape, roads, buildings (mainly roofs), parks, etc. in a bird's eye view, which can be seen on the monitor of the center. However, in reality, even when looking at the city from the top, it takes a considerable amount of experience to identify and recognize the facilities in the city, except for some landmark facilities. Also, the camera moved and the landscape changed. Sometimes it is difficult to instantly grasp the contents and details of the landscape.
