It is a method of surveying a route such as a stream, path, or the edge of an outcrop by means of a series of traverse legs, of each of which the bearing is observed by compass and the length measured directly in the field.It may be described as a zig-zag. Make sure each team has a compass, clinometer, measuring tape, and field notebook. A compass traverse is a method of filling in detail on a topographic, geologic, or other map. Traverse Correction Procedure Chain, Tape, Ranging Rods, Arrows, Cross Staff. and surveying procedures all have a direct influence on the survey measurements and thus, the derived survey control mark positions and uncertainties. In this post, I am going to discuss about to survey an open field by chain surveying in order to calculate the area of the open field. The survey is done mainly to make maps and plans for construction projects. Progress around the traverse adding Latitudes algebraically to obtain the N-S (Latitude) coordinates at each station. A traverse is a series of connected lines whose lengths and directions are to be measured and the process of surveying to find such measurements is known as traversing. Chain surveying can be used when the area to be surveyed is comparatively small and is fairly flat. ENGI3703- Surveying and Geomatics Fall 2007 Memorial University of Newfoundland 4 Instruments to be used: Check out the following equipments: ♦ Total Station/digital theodolite ♦ Tripod ♦ Prism/tape ♦ Pegs Procedure: 1.

Field procedure. It is however pivotal to understand the underlying concepts of open traverse calculations and closed traverse … D. SCOPE OF MANUAL This MANUAL, in general, covers Division-wide surveying policies and procedures and appropriate reference material. These closed traverse surveys have many applications like fixing the boundaries of ponds, forests etc. Balancing the Closed Traverse in Land Surveying . What is theodolite? Traverses may either be open or closed. It is also used in geodesy.Traverse networks involve placing survey stations along a line or path of travel, and then using the previously surveyed points as a base for observing the next point. Equipment used to find the area using chain surveying. At least one person on each team should have taken ESRM 250 or have experience using ArcGIS. Nor is it a substitute for surveying knowledge, experience or judgment. Traverse Surveying is a popular method of surveying. TAYLOR’S UNIVERSITY | SABD | SITE SURVEYING (QSB 60103) | TRAVERSING REPORT 9 2.0 OBJECTIVE To learn the principles of running a closed field traverse. Procedure for surveying the given open field (Closed Traverse): Note: This procedure is general procedure only. Since the main survey line must form a well-conditioned triangle in chain surveying, the importance of reconnaissance increases. Open traverse (ii) Unclosed or open traverse:- A traverse is said to be open or enclosed when it does not form a closed polygon. Using a Total station/theodolite, run a closed traverse such that it includes the two Tacheometry is a branch of angular surveying in which the horizontal and vertical distances are obtained by optical means as opposed to the ordinary process of chain and tape. In this article, we will discuss the definition of traverse surveying, types, methods and checks etc. Surveying is an important step for any type of project. In this fieldwork, we are able to practice and carry out the closed loop traverse survey that is located at the Taylor’s University Block E car park. The product of an open compass traverse is always a polyline. Field Procedure of Chain Surveying. Closed traverse survey using total station has particularly become popular in recent times. It is used to measure the angle of two points. Form teams of three. Surveying for Central Station, Sydney, 1900 Surveyor needs a lot of knowledge from math, geometry and being a surveyor was admired and honorable career This website is being made for subject Surveying Course and is based on book Surveying Fundamentals and Practises , 6th edition, Pearson. This Guideline outlines ICSM’s recommended equipment and procedures for conventional traverse surveys, and provides examples for the evaluation of the uncertainty of estimated Traverse networks involved placing the survey stations along a line or path of travel, and then using the previously surveyed points as a base for observing the next point. For complete traverse computations, the following steps are usually necessary. Example 1: 1. To enhance students’ knowledge in traversing procedure. If the traverse formed by the survey lines closes at a station i.e. This procedure varies with the experiment given to students. Closed traversing is generally used for locating the boundaries or for surveying of large areas. In this article, we show all information about theodolites like parts of the theodolite, survey of theodolite, and classification of theodolite, theodolite traversing, and the process of theodolite traversing.. What is theodolite? Traverse the stations as indicated in the assignment instructions. Traverse surveying is very important in civil engineering. This procedure provides a check on the balancing procedure and gives the coordinates of each station on the traverse. This is done with the help of two special type of instruments- transit theodolite and stadia rod. if the survey lines form a polygon or starts and finishes at the same survey station of the known co-ordinates then the traverse is known as closed traverse. Tomas U. Ganiron Jr. IPENZ, ... this point, the procedure was to add the two departures of each area and m ultiply the sum by . An instrument used for measuring horizontal and vertical angles accurately is known as a theodolite. To establish ground control for photographic mapping. A compass is an instrument that is small in size. The chief methods by which the direction of the survey lines may be determined are as follows. 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. Gales Traverse Table-Definition, Procedure and Table. Thanks to and with permission of Nick Hopton (UK). teaching about standing a theodolite and traverse procedure As already stated in the last section, surveying which involves a series of connected lines is known as ‘traversing.’ The sides of the traverse are known as ‘traverse legs’. Traverse is a method in the field of surveying to establish control networks. 1.8.4. The process of surveying is therefore in three stages namely: (i) Taking a general view ... traverse station is each of the points of the traverse, while the traverse leg is the straight line between consecutive stations. The traverse begins on a control point and ends on another control point. Traverse surveying has been one of the most basic survey types being used for ages by surveyors. Closed Traverse. The practice may be more precisely described as land surveying to distinguish it from quantity surveying, building surveying and other forms of surveying. Reconnaissance: Before the actual survey starts, the surveyor simply walks around the site.This helps the surveyor to select the main stations. The procedure used for making gales traverse … Open traverse: When a sequence of connected lines extends along a general direction and does not return to the starting point, it is known as ‘open traverse’ or ‘unclosed traverse’. Traverse is a method in the field of surveying to establish control networks. understanding of surveying and its proper relationship to other Administration activities. T raverse in surveying is the series of connected survey lines whose distance is measured with the help of tape & chain and direction is measured with the help of compass or theodolite, from one point to another point in the field is called traverse in surveying..
