Types of Surveying and mapping instruments for surveying and Mapping Instruments

Answer:

An instrument for measuring horizontal angles and vertical angles. It consists of a telescope, a horizontal dial, a vertical plate and a base. Theodolite is widely used in control, topography and construction lofting, and other measurements.
An instrument for measuring the difference between two points. It consists of telescope, level (or compensator) and pedestal. Level is widely used in control, topography and construction, lofting and other measurement work.
The instrument is the main instrument for manual surveying and mapping of large scale topographic maps. Composed of alidades, plate and the support member. If you add the electromagnetic wave distance measuring device in alidades, accelerate the progress of the work of Surveying and mapping.
