Monitoring of the wut grand hall roof in conditions of high temerature changes

Geodetic control measurements of changes in geometry an object should satisfy high accuracy and reliability. New techeometers equipped with Automatic Target Recognition automatically moves the telescope to the prism and supports control point measurements. The accuracy of using an ATR system and the stability of an instrument in precise measurements were present the results of monitoring measurement were controlled in laboratory and field conditions. This paper will present the results of monitoring measurements with a Leica TDA 5005 during the investigations of roof geometry in conditions of high temperature changes.
