Proper care in the use, storage, transportation and adjustment of the equipment is a major factor in the successful completion of a survey. Control Survey / Traverse: It is similar to any type of EDM Traverse. Advantages and disadvantages of online survey methodology are reviewed. The primary advantage of using EDM devices for land survey measurements is the speed and accuracy with which they deliver readings. opens new possibilities for one-person surveying, increased productivity, and improved personal safety. DR is achieved using either of two EDM technology methods: Time of Flight (Pulsed Laser) or Phase Shift. Lecturer, ** Senior Technical Assistant Department of Mining Engineering, Indian School of Mines, Dhanbad - 826004 ABSTRACT Although surveying techniques have … They have a range up … Depending on the type, laser tape measures can also work with much longer distances. This has become possible because of introduction of electronics in these measurements. When direct reflex combines with robotic technology, the possibilities for one-person surveying increase even further. 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. MODERN SURVEY INSTRUMENTS AND THEIR USE IN MINE SURVEYING P.P. The next article will cover each step of the computation to reduce an EDM measured distance to the corresponding grid length. It also consists of a micro … 3. 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. Bahuguna**, Dheeraj Kumar**, Sunil Kumar*** *Associate Professor, ** Sr. Most of the quantities can be converted by transducers into the electrical or electronic signals. 10,000 distortion into any final surveying work product. 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. You will see how the elevation and the scale factor are used in the … Hopefully, the myth has been dispelled and I have captured your attention. Advantages of Electronic Measurement The advantages of an electronic measurement are 1. 2. The downside to laser tape measures is that … 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. 1.8.3. An electrical or electronic signal can be amplified, filtered, multiplexed, sampled and measured. They need only to be placed in one area and faced toward a hard surface of another area to correctly gauge a distance. There are three primary types of commonly used surveyor instruments for EDM: Microwave instruments – These instruments use microwaves to take survey measurements. The main advantage with laser tape measures is the speed at which they work. 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.
