We conducted a measurement accuracy and laborsaving in the spraying slope frame work by appli-cation of ICT earth works using UAV was verified by using field of actual work? In the UAV survey? it was possible to apply the Ministry of Land? Infrastructure? Transport and Tour-ism (MLIT) standards to the UAV survey by facing front of a slope? The measurement accuracy of the cross-sectional measurement of the frame was ensured by setting the frame cross-section at 5 mm/pixel and 90% wrapping, and In the area measurement? a difference of -1% to +2% could be calculated? The introduction of UAV is expected to significantly reduce the time required to work in the field on steep slopes? The measurement of a 1500m2 of a field was completed with about 50% less labor than the conventional method?
