DEVELOPMENT OF POSITIONING INFORMATION REALIZED DIGITAL CLOSE- RANGE PHOTOGRAMMETRIC SYSTEM

Digital photogrammetric system has shown many possibilities in image analysis division for real time digital photogrammetric treatment use of the digital camera which take storage capacity itself and digital photogrammetric measuring method. And GPS, positioning system using satellites, is acquired its utilities in many parts because it is very easy to get the three dimensional coordinates using GPS around the world. In this research, in comparison with Precise Control Point Surveying used GPS(Sokkia GRS2600), Ordinary system(Nicon D200+GPS101) and development of positioning information realized digital close-range photogrammetric system(Nicon D200+GPSmap 60CSx) surveying results, Ordinary System surveying latitude error is 19.383m, longitude error is 9.090m and Altitude error is 8.413m. However development system has shown that latitude error is 7.203m, longitude error is 4.544m and altitude error is 5.735m. Also, consumption of battery is one of the most important things for photogrammetry, the old system can observe about 30 pictures but development system can observe about 200 pictures and the weight is lessen than 3kg so that one person can operate alone. Therefore, the point of development of Positioning Information realized Digital Close-Range Photogrammetric System is to increase efficiency when renewing old result of digital map for changed topography rapidly and when you need real time information
