Important progress in electronic surveying has been made in the past four years. Particularly notable are the increased availability of commercial instruments for electromagnetic distance measurements, the initial development of very long base line interferometry (VLBI) for geophysical measurements, and the efforts to determine atmospheric refractivity by dispersion, Raman lidar, and radiometry.
