Title: Ultimate Precision of Barometric Surveying

Author(s): Victor Vacquier (2)


By constructing two aneroid barometers which could be compared with an instrumental precision equivalent to 0.3 foot of elevation difference, it was possible to obtain a measure of the errors of barometric surveying which originate solely from atmospheric disturbances. It was found that in fairly level country, under average weather conditions, the contribution of atmospheric disturbance to the probable error of a single elevation observation is 0.96 foot when two aneroids are 3 miles apart. Practical applications and methods of carrying out elevation surveys are discussed.
