Description:

The National Geodetic Survey (NGS), a component of the National Ocean Survey, NOAA, conducted leveling refraction tests at a site near Gaithersburg, Md., during july-September 197 9, and at a site near Tucson, Ariz., in April 1980. The tests were designed to measure refraction errors between bench marks at sight distances of 30, 4 5, 50, and 60 m by comparing nominal2-meter refraction-free elevation differences to observed elevation differences containing refraction errors. The refraction-free elevation differences were determined using sight distances of 13 m or less.
