BASICS OF SURVEYING 1.1 SURVEYING DEFINED Surveying is the art of measuring distances, anglesand positionson or near the surface of the earth. 3. surveying notes ,study material, assignment, lectures is helpful for technical universities & engineering college students to learn his surveying syllabus. Work from Whole to the Part 37. A standard transit is a telescope that consists of crosshairs for sighting a target. Instruments using light or IR waves are classified as electro-optical instruments.Instruments based on radio waves are generally called microwave instruments.Because of the different structure of these two types of instruments, they will be discussed separately. to divide the area into number of triangles of suitable sides. Surveying notes for civil engineering students.Learn surveying , process , analyze and help to design a plan for construction. Figure 2 shows, the research done in various areas of EDM process for improving its performance measures. 8.11 EDM without Reflecting Prisms (Reflector Less Measurements) 8.12 Focussing and Sighting. A network of triangles is preferred here as triangle is the simple plane geometrical figure which can be plotted with the lengths of its sides alone. Consolidates the theory of plane surveying with practice and gives experience in organization and team working on a surveying projects. Surveying or land surveying is the technique, profession, art, and science of determining the terrestrial or three-dimensional positions of points and the distances and angles between them. 8.1 Introduction. CHAPTER 12 ELECTRONIC SURVEYING EQUIPMENT Chapter 12 of the EA3 TRAMAN introduced you to electronic surveying equipment, specifically electronic distance-measuring equipment. SVG205 Surveying II A Instrumentation: (1) Optical theodolite; construction, errors, tests and adjustment, (2) Electronic Distance Measurement (EDM): construction, errors, tests, adjustment and standardization. 2 • Surveying has to do with the determination of the relative spatial location of points on or near the surface of the earth. Compass Surveying – Principles use of Prismatic Compass, Measurement of Ranging rods are used to mark the corners of each triangle and a sketch is drawn in the survey book showing the survey lines and giving each point a station reference (usually alphabetical). surveying notes ,study material, assignment, lectures is helpful for technical universities & engineering college students to learn his surveying syllabus. Some of the modern surveying instruments are discussed in … If the instrument is reset (zeroed) TH will be 0.0 so if you make a REM measurement with TH=0 the For calculating the telescope inclination angle and telescope rotation angle, the telescopes combine with scales, all total stations consist of an electronic angle scanning device and EDM instrument. Working principle of E.D.M Author: Technical Editor Category: Civil Engineering 9 May 18 These operate on the principle that transmitter at the master station sends modulated continuous carrier wave to a receiver at the remote station from which it is returned. It is designed for civil engineering students & professionals to explore surveying skills. Because only a surveyor who has full understanding of surveying techniques will be able to determine the most efficient methods required to obtain optimal results over a wide variety of surveying problems. With modern surveying instruments, survey work will be precise, faster and less tedious. This chapter is intended to supplement what you learned in the EA3 TRAMAN discussion, and, in addition, introduces you to the basic principles and uses of other types of electronic surveying equipment. Proper care in the use, storage, transportation and adjustment of the equipment is a major factor in the successful completion of a survey. Surveying notes for civil engineering students.Learn surveying , process , analyze and help to design a plan for construction. This course is also useful for fresher’s to jump in real surveying industry directly. Trouble-Shooting the REM Measurement The only numerical input is the target height so make sure that is entered correctly. Electronic Distance Measurement (EDM) is a fundamental feature of modern surveying Total Stations.

Instead, the principle of EDM is based on the following relationship: L = 0.5(m + p) λ. m. is an integer number of whole wavelengths, p. is a fraction of a wavelength (is measured by EDM). Electrical Discharge Machining Fundamental Manufacturing Processes Video Series Study Guide - 1 - Training Objectives After watching the video and reviewing this printed material, the viewer will gain knowledge and understanding of electrical discharge machining, or EDM, principles and capabilities.
