Abstract

Cultural heritage field survey is one of the important research methods that can estimate the approximate distribution, the range and the features of the archaeological site on the buried cultural heritage distributed in the area by conducting a preliminary survey on the appropriate area before a large scale development of the targeted area. However, a result of the field survey has only been plotted on the paper map. Therefore, there have been several problems because of the limitation to the additional use such as the location analysis and feature understanding of the archaeological site except for the position display. Thus, in this study, it has been able to confirm the accurate archaeological site location by performing three dimensional modeling on the ground cultural heritage and applying digital photogrammetry to solve the existing problems of the survey and drawing making of the cultural heritage. This study also suggested a method to obtain specific and accurate information. In addition, the three dimensional space error by digital photogrammetry got a positive result, 5.32㎜. As a result of the comparison between the survey and volume of RTK GPS, the relative accuracy was calculated 2.1 percent and it showed a positive result. Therefore, it was able to confirm that digital photogrammetry, a non contact measurement method, was quite useful for Cultural heritage field survey.
