Recently, UAV(Unmanned Aerial Vehicle) has been used in various fields beyond the simple application
for a military operation. In this study, ortho image were constructed about study area using UAV for
analysis of characteristics by type of terrain model. Ortho image were normal ortho image by DTM(Digital
Terrain Model) and true ortho image by DSM(Digital Surface Model). And comparing the produced images
were performed. There are no distortion around the building in normal ortho image but it appears shadow
area around the building. So, normal ortho is expected to be utilized for general services such as image
map service. However, true ortho image seems high usability in the surveying field. If the distortion would
be complemented around building through further studies, true ortho image will be used in various surveys.
