It is necessary to search the road image displayed in the image area 10 at a point necessary for changing the reproduction speed of the image in the speed adjustment area 11 displayed by selecting "operation" in the operation area 20, or the traveling speed. Search by fast-forwarding the road image corresponding to.

During the search, the images of the up lane and the down lane of the route are switched and displayed by the selection instruction of "up" or "down" on the operation unit 2. Further, in order to search for the road condition at the kilometer from the base point of the route, the road condition at each point is entered by inputting the kilometer at the ten-key area 12 which is also displayed by the selection instruction of "km" of the operation unit 2. In the search of, the image area 1 is input by inputting an instruction of the point by the point list display area 13 which is also displayed by the selection instruction of the “point” of the operation unit 2.
Road images corresponding to 0 are output.

Similarly, to search for signs, lights, information boards, etc. recorded and stored on the optical disc in relation to the road image, "photograph" of the operation unit 2 is used for searching the road plan, and "photo" of the operation unit 2 is used for searching the road plan. “Plan view”, “inside view” of the operation unit 2 for searching inside views, and the same as the operating unit 2 for searching mosaic photos.
It is only necessary to select and indicate "vertical".

For river management, the river image shall be obtained, for example, by video recording from water navigation or in the air, and the type of levee, riverbed condition, dam structure / form and bridge in each river to be managed. The situation, water intake, and other general conditions of the river. This river video is searched in the same manner as the above-mentioned road video search, and after selecting each river within the jurisdiction by its name, the situation of each river is output as an image. Then, for example, a display of search means such as "diagonal" for displaying a slant at each point of the river, "bank" for displaying a dike type, "low waterway" for displaying a low waterway is displayed in the operation area 20 and can be searched. It is like this.

[0033]

The present invention is configured as described above,
Therefore, when searching for the road / river status at any point on each route / river that is being managed by various road / river management facilities, a video of the road / river situation that was previously video-recorded is taken. You can instantly search and output images, and in that search, you can switch the road and river images in the up and down directions at the point by inputting the kilometer mark from the base point of the route and river and inputting a specific point. Output can be displayed. Therefore, when dealing with various situations such as disaster response, daily work, etc.
The river situation can be grasped promptly and appropriate measures can be taken.
