USE OF NEW METHODS IN TOPOGRAPHICAL WORK

UTILISATION DE METHODES NOUVELLES POUR LES TRAVAUX TOPOGRAPHIQUES

The progress achieved in electronics has allowed for the development of electro-optical telemeters adapted to all requirements for the study of new line lay-outs. The "Geodimetre A 6" unit used by the SNCF in establishing the polygonation of a section of the new Paris-Lyons line serves as theodolite, length measuring device and tachymeter. For topographical considerations, the tape- recorded data can be exploited by computer or calculating machines linked to tracing tables.
