Webbtheodolite"(Cyclopaedia, vol. 2).Even as late as the 19th century, the instrument for measuring horizontal angles only was called a simple theodolite and the altazimuth instrument, the plain theodolite. The first instrument more like a true theodolite was likely the one built by Joshua Habermel (de:ErasmusHabermehl) in Germany in 1576, WebbTo use theodolite to measure the horizontal angle. THEORY: The theodolite is the most precious instrument design for the measurement of horizontal and vertical angles and has wide applicability in surveying such as laying off horizontal angles, locating points on line, prolonging survey line, establishing grades, determining difference in elevation, setting … WebbTheodolite is a precision instrument whose main purpose is for measuring angles in the horizontal and vertical planes.
