Abstract:

Three new instruments for precision leveling have been developed at the University of New Brunswick the Photoelectric Laser Level the LaserNi-007, a combination of He-Ne laser with the Zeiss-Jena Ni-007 geodetic level a Self-Aligning Centering Detector for laser leveling with long sights in a turbulent atmosphere. The instruments have been laboratory and field tested in a differential geodetic leveling and in leveling across rivers. First-order geodetic accuracy has been obtained. Author
