advantages of edm in surveying

DR is achieved using either of two EDM technology methods: Time of Flight (Pulsed Laser) or Phase Shift. Definition of Traverse: – Traverse is the method of control survey in providing horizontal and vertical controls along a pre-defined route by means of establishing a series of connected lines joining the traverse stations. Most of the quantities can be converted by transducers into the electrical or electronic signals. It also consists of a micro … When direct reflex combines with robotic technology, the possibilities for one-person surveying increase even further. MODERN SURVEY INSTRUMENTS AND THEIR USE IN MINE SURVEYING P.P. The main advantage with laser tape measures is the speed at which they work. MODERN SURVEYING EQUIPMENT Revolutionary changes have taken place in last few years in surveying instruments that are used for measuring level differences, distances and angles. Control Survey / Traverse: It is similar to any type of EDM Traverse. 3. They need only to be placed in one area and faced toward a hard surface of another area to correctly gauge a distance. Surveying Equipment, Measurements and Errors 3.1 EQUIPMENT The procurement and maintenance of surveying equipment, tools and supplies are important parts of the Department’s survey effort. 2. Advantages of Electronic Measurement The advantages of an electronic measurement are 1. Depending on the type, laser tape measures can also work with much longer distances. There are three primary types of commonly used surveyor instruments for EDM: Microwave instruments – These instruments use microwaves to take survey measurements. The next article will cover each step of the computation to reduce an EDM measured distance to the corresponding grid length. Lecturer, ** Senior Technical Assistant Department of Mining Engineering, Indian School of Mines, Dhanbad - 826004 ABSTRACT Although surveying techniques have … The exploitation of electronic distance meters (EDM) in surveying practice, their rapid development in terms of construction, especially concerning the range and accuracy of measured distances, has led to the formation of a range of new methods and procedures in the area of measurement processing. An electrical or electronic signal can be amplified, filtered, multiplexed, sampled and measured. Hopefully, the myth has been dispelled and I have captured your attention. 10,000 distortion into any final surveying work product. Proper care in the use, storage, transportation and adjustment of the equipment is a major factor in the successful completion of a survey. You will see how the elevation and the scale factor are used in the … Advantages and disadvantages of online survey methodology are reviewed. 1.8.3. The primary advantage of using EDM devices for land survey measurements is the speed and accuracy with which they deliver readings. Bahuguna**, Dheeraj Kumar**, Sunil Kumar*** *Associate Professor, ** Sr. Total Station is an equipment used in surveying, designed for measuring horizontal and vertical angles, inclusive of measuring sloping distance of object to the instrument.It is a combination of electronic theodolite and electromagnetic distance measuring (EDM) instrument.
