A slope distance AB XX m measured with EDM, if vertical angle is 01° 14' 20" and elevation of point A is 426.546m and height of instrument is 1.5m and height of target is 1.7m. The prism constant is -30mm, the pressure and temperature correction is 15 ppm and scale factor correction is 1.0004. Find: • The corrected horizontal distance AB projected on local map. • The corrected horizontal distance AB projected on national map (radius of Earth 6375 km). The relative error due to neglecting sea level correction. • The accuracy of the corrected distance if EDM accuracy is ± (3 mm +3ppm). • XX=Last six digits from your ID divided by 100 (e.g., ID 900172567 XX=1725.67)
