What is a theodolite?

Answer 1

A theodolite is a Surveyor's measuring instrument that began to take its present form in the 17th century. In the work, 'The Surveyor in Foure Books' by Aaron Rathborne (London, 1616) an elaborate drawing of a theodolite can be seen on the front piece. These were used as early surveying tools, and were extremely acurate. Thomas Jefferson used such an instrument during his time as a surveyor. Later versions are also known as "Dumpy Theodolite", while 20th century versions use extremely fine optics, or lasers. The tool in it's present,modern versions is indespensible as a surveying/mapping tool. Wala lang...Kervin to of BSCE 3-1 PUPSMB
Theodolites- pronounced as it is spelled, are surveying instruments of high precision and accuracy. They are a more sophisticated form of what is usually called a transit. The Theodolite is always operated from a tripod and has Base (circular) and Cylindrical levels on the instrument to keep it level. The name is thought to derive from the Greek- approximately ( The Eye of God). Modern engineering, building and bridge construction, etc, even mining, could not function without the theodolite and the more modern derivatives using electronic devices and GPS. ( progress in full swing, as with Cameras and electronic measurement of parameters, as with modern non-digital Nikons.) By the way Nikon makes theodolites. One of the best historically and by no means an obsolete instrument was/is the Wilde-Zeiss theodolite which reached its present form around l938. a common sight on Gotham building sites. Their uses are many!
