SurveyingSurveying instruments are used for measuring angles and, when using total stations, they also measure distances. Transits and theodolites were formerly used for measuring angles. These were mechanical and optical instruments which measured horizontal and vertical angles. Now, digital Total ...

This is an instrument used for measuring angles in surveying, and it is also marked with lines and scales which can be used for making calculations. There is an optometer invented by Thomas Young for testing eyesight and prescribing spectacles, there are early telescopes with vellum tubes, ...
A total station is an electronic/optical instrument used in modern surveying. The total station is an electronic theodolite (transit) integrated with an electronic distance meter (EDM) to read slope distances from the instrument to a particular point. ...
THIS volume fills a gap that has been long felt in consequence of the great dearth of good books treating of instruments used for surveying and levelling. Various books and pamphlets contain descriptions and methods of using instruments of this class, but there is no work in which each ...
