Geodetic refraction
WebNov 1, 1986 · The atmospheric refraction is one of the factors which limit the precision of any type of geodetic work. The methods for the determination of its effect can and should be improved. The field is very ample. Thus we have to restrict ourselves to a few examples of how the treatment of the refraction may be improved. WebAbstract. THE memoir before us is concerned with the correction for refraction in geodetic operations between distant stations, especially those differing considerably in altitude. …

Terrestrial refraction, sometimes called geodetic refraction, deals with the apparent angular position and measured distance of terrestrial bodies. It is of special concern for the production of precise maps and surveys.
