To create drawing of profile leveling and cross leveling or calculation of Earth volume in the
construction surveying, survey using GNSS and Total Station should be required a lot of time and labor
force. In this study, aerial photo were captured by UAV(Unmanned Aerial Vehicle). DSM(Digital Surface
Model) and ortho image were generated and cross leveling was produced by 3D point cloud. As a result,
It was greatly to shorten the work process about cross section drawing using UAV data the data in near
real terrain. In addition, volume calculation was performed and volume for cutting and banking effectively
The UAV data to calculate the volume of the effective area, without any additional processing because it
can set a target area range as desired. It could propose the utilization of UAV in the cross section
surveying and volume calculation and improvement of the efficiency of the surveying business and
economics is expected.
