Surveying is the art of determining the relative positions of the points above, on, or below the earth's surface by the means of direct or indirect measurements. This implies a precise control surveying as the first consideration followed by subsidiary detail surveying. As the total work is divided into parts, the error of one part will not influence the other parts. Principles of Traversing: The traversing is the field method which is used for delivering the control of different networks. 1. 1.2. What is principle of surveying? The dumpy level is a two-man procedure, one may require at least an assistant to proceed with the operation. It's a great solution if you need to free up some time. With the help of chains, surveyors take length of straight lines that define the skeleton or framework in an area. a) True. 2 • Surveying has to do with the determination of the relative spatial location of points on or near the surface of the earth. Surveying is the first step . Principles of Compass Surveying. the principle of the measurement device in edm, which is currently used in a total station and used along with electronic/ optic theodolites, is that it calculates the distance by measuring the phase shift during the radiated electromagnetic wave (such as infrared light or laser light or microwave) from the edm's main unit, which returns by being … Concept: Plane table surveying is the graphical method of survey in which the field observations and plotting are done simultaneously..

It includes the determination of the measurement data, the reduction and interpretation of the data to usable form, and, conversely, the establishment of relative position and size according to given measurement requirements. In fact, every question should tie back to a specific objective. Compass Surveying • Chain surveying can be used when the area to be surveyed is comparatively small and is fairly flat. This is determined by taking measures such as the relative positions of the various points, their distance, direction, and height. The general principles of surveying are: To work from the whole to the part To locate a new station by at least two measurements (linear or angular) from fixed reference points. Plane table surveying is based on the principle that lines drawn during plotting always lie parallel to the corresponding lines actually present on the ground i.e the principle of plane table surveying is parallelism. Plane surveying considers the earth to be a flat surface--a plane, which works well for jobs spanning a short distance (a few . close. The surveyed points for the base observation. By using various tools, a land surveyor can measure things such as elevation, angles, and boundaries on a property. b) False. • Survey design • Survey quality Although taping and theodolites are used regularly on site -total stations are also used extensively in surveying, civil engineering and construction because they can measure both distances and angles. The chapter contains background information and references that support the standards and guidelines found in the previous chapters. The Top Five Principles of Good Survey Design.
