The horizontal distance (L2) of the can be obtained, as shown in Figure 8, by calculating the horizontal distance (L2) and the azimuth angle (θ2) data output from the azimuth measuring device 80, the laser range finder 40 The distance in latitude and longitude of the reference point 2 centered can be calculated. The latitude and longitude distances of the reference point 2 configured as described above and the coordinate data output from the GPS receiver 70 may be calculated to calculate the latitude and longitude coordinates of the reference point 2.

Therefore, when the operator uses the input device 120 to direct the laser range finder 40 toward an arbitrary reference point 2 and then inputs a control command, the operation unit 114 determines that the reference point 2 Coordinates are calculated and the calculated coordinate data are output to the data synthesizing unit 116.

When the coordinate data of the reference point 2 output from the coordinate calculating unit 115 is output, the data synthesizing unit 116 synthesizes (adds) the coordinate data of the output reference point 2 to the image image data and inputs the input device ( The image image data is output to the wireless transmitter 140 according to the control command inputted by 120.

In detail, the digital map synthesizing unit 4c receives image data including coordinate data of the reference point 2 on the image image and coordinate data on latitude and longitude of the measured reference point 2, After adjusting the magnification of the video image so that the coordinate data of the digital map data and the coordinate data of the reference point 2 included in the video image data are matched, the digital map using the video image is synthesized by combining the video image with the digital map data. Data can be produced.

The method of activating the digital image digital map editing system using the digital map editing system configured as described above is as follows.

First, the operator determines a point that is easy to survey as the reference point 2, sees the aerial image image displayed on the monitor 130, clicks and inputs the position of the reference point 2, and then monitors 130 ), A control command is input to display an image photographed by the observation camera 50.

When the laser range finder 40 is directed toward the reference point 2 while the input device 120 is operated while viewing the image displayed on the monitor 130, the controller measures the coordinates of the reference point 2. After synthesizing the coordinates of the corresponding reference point 2 to the image image data, the wireless transmitter 140 outputs the coordinates of the reference point 2 to the wireless receiver 4a of the editing apparatus 4.

Therefore, by using the editing device 40, by receiving the synthesized video image of the coordinate data of the reference point 2 and synthesizing it into the digital map, it is possible to produce a digital map using the video image.

In addition, when the height of the observation camera 50 and the laser range finder 40 is so low that the view is obstructed by a variety of nearby obstacles or other obstacles, the operator as shown in Figure 9, the lifting unit 20 The auxiliary lifting bar 24 is connected to the lifting bar 21 as much as necessary, and the lifting driving device 25 is operated to move the rotating plate 30, the laser range finder 40, and the observation camera 50 upward. By moving, the survey can be carried out undisturbed.

In this way, the geographical information image image numerical map editing system according to the change of the aerial photographing position is configured by the operator by setting an arbitrary reference point 2 on the aerial image data, and measuring the latitude and longitude coordinates of the set reference point 2. After inputting automatically, it is wirelessly transmitted and edited by the editing apparatus 40 automatically, so that it is very convenient to use, and there is a vertex that the numerical map editing is very quick.

In addition, by connecting the auxiliary lifting bar 24 as necessary to the lifting bar 21 of the lifting unit 20 to raise the laser rangefinder 40 and the observation camera 50 provided on the rotating plate 40 and the rotating plate.
