It was described in the appendix by Martin Waldseemüller, a German topographer and cartographer, who made the device in the same year.waldseemüller called his instrument the polimetrum. GregoriusReisch showed such an instrument in the appendix of his book Margarita Philosophica, which he published in Strasburg in 1512(Maurice D., 1989).
It was only a matter of time before someone put two measuring devices into a single instrument that could measure both angles simultaneously. INTRODUCTION Prior to the theodolite, instruments such as the geometric square and various graduated circles and semicircles were used to obtain either vertical or horizontal angle measurements. Key words: surveying,evolution,theodolite. The paper aims to highlight the improvements made over time on this instrument in constructive and operational terms. A theodolite is a precision instrument for measuring angles in the horizontal and vertical planes. One of the surveying instruments is the theodolite.
