Equipment for Complete Mechanisation 1. Surveying Equipment Theodolites A theodolite is an instrument for measuring both horizontal and vertical angles, as used in triangulation networks. It is a key tool in surveying and engineering work, particularly on inaccessible ground. A modern Theodolite consists of a movable telescope mounted within two perpendicular axes—the horizontal or turn-on axis and the vertical axis. When the telescope is pointed at a desired object, the angle of each of these axes can be measured with great precision, typically on the scale of arc seconds. • Total Stations - 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 distances from the instrument to a particular point where an assistant staff holds refector. Robotic total stations allow the operator to control the PG 40 Built ExpressionsBuilt Expressions PG 40 Vol: 3 Issue: 11 November 2014
