Before revision: Application Typical distance measurements were between mountain tops A tellurometer being set up at night by the National Geodetic Survey The tellurometer design yields high accuracy distance measurements over geodetic distances, but it is also useful for second order survey work, especially in areas where the terrain is rough and/or the temperatures extreme.
