In a study of permafrost melt beneath Arctic streams we conducted 3D surveys in remote locations that required spatial (horizontal and vertical) precision on the order of 2 cm. Integrating kinematic geodetic grade GPS measurements with GPR data acquisition provided the necessary spatial control. 3D migration produced
