High precision survey at LKAB mine

Home / News / High precision survey at LKAB mine

An Iron-ore mining site in Kiruna, Northern Sweden, was recently repeatedly surveyed with a SmartOne on two different dates. Results show that the point measurement accuracy was 0.8, 0.8 and 1.3 cm (RMS) in Easting, Northing and Height. The height accuracy (RMS) of individual grid points in the surface model (DSM) was 3 to 4 cm for smooth and vegetated horizontal surfaces and 5 to 8 cm for steep smooth and rough surfaces.
