What is Orientation? Closed traversing is generally used for locating the boundaries or for surveying large areas. The imperfections of the instruments The fallibility of the humanoperator The uncontrollable nature of the environment Errors always exist in measurements, where: The error (The error (eeii))= the measured value (x= the measured value (x ii)) --the true value (x)the true value (x) For adjusting the traverse, which of the following methods can be used? The error occurs due to wrong measurement of lengths and bearings of lines in the field and due to faulty plotting. a. Types of Traverse in Surveying The traverse may be categorized into the following types: 1. Open Traverse: When a sequence of connected lines extends along a general direction and doesnt . or starts at a known points and ends at a known point. Surveying is the science and art of measuring distances and angleson or near the surface of the earth. 27. not revealed. This subtraction provides the angular error with the appropriate sign. • Traversing is the most important act of determining relative ground positions of points. Closed Traverse: If the traverse formed by the survey lines closes at a station i.e. Fig 2.1 (a) Closed traverse is suitable for the survey of boundaries of ponds, forests etc. second. a.

Ganiron Jr. IPENZ, Auckland City, NZ College of Architecture, Qassim University, Buraidah City, KSA E-mail address: tomasuganironjr@gmail.com ABSTRACT This descriptive research focuses on the role of land surveying in the development of an when it returns to the . A closed traverse is a series of connected lines whose lengths and bearings are measured off these lines (or sides), which enclose an area. 10m interval from a survey line to an irregular boundary line. The first surveying exercise included is a traverse pacing exercise. These surveys are of high precision and extend over large areas. These two lines are done by some previous survey, and are very accurately done this is our high order survey. A closed traverse can be used to show the shape of the perimeter of a fire or burn area. Surveying is an orderly process of acquiring data relating to the physical characteristics of the earth In this laboratory, individual group member's paces and a compass were used to determine rough values for the lengths and relative angles of the traverse legs. 6. 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. While plotting a closed traverse, the starting and the ending points seldom coincide, and this discrepancy by which the ending point fails to meet with the starting one is called the closing error or error of closure. WSDOT TSS survey specifications are to be used for all WSDOT involved transportation improvement projects, including special-funded projects. A traverse is a survey where you have occupied each station and measured each angle and distance between points. Also I have described about Traversing: what are the types of Traverse (closed traverse, Open Traverse), Traverse calculations and adjustment of closing errors, traverse precision, latitude and departure, Bowditch Rule/Compass Rule, Transit Rule etc. 22. To avoid the accumulation of errors, extensive surveys should proceed from the whole to the part, by first establishing a network of primary triangulation points. 3.5 Procedure for balancing a closed traverse The following four-point traverse was conducted in the field to determine the area of the enclosed parcel of land: Station' Direction' Distance' Slope'' A' ' ' ' ' 58 o ' 102' 0' B ' ' ' ' 109 'o ' 130' 0' C' ' ' ' ' 213 'o ' 132' 0' D' ' ' ' ' 306 'o ' 172' 0' A Total' ' 536' ' 1. 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. If you have a 10 point traverse we shoot 1 in as 11 and 12 in as 2. for the survey suitable boundaries of ponds, of forests estates. TRAVERSE CLOSURE COMPUTATIONS FIGURE 7-12.

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). Angles are measured by theodolites or total stations; the distances can be measured by electronic distance measurement (EDM) instruments, sometimes by steel tapes. (6) b) The following readings were taken in a running closed compass traverse. It is also defined as surveying traverse whose correctness may be determined by the fact that the angles should add up to 360 degrees when it is closed (as a close polygon has 360 angle), and which terminates at its starting point. In the survey network it wants a direction. Well, I know the bearing of this line, and then I am measuring the bearing of all these lines. The sum of interior angles must be equal to_____ a) (2N+4) right angles b) (2N-4) right angles c) (2N+4) * 180 d) (2N-4) * 180 Answer: b Clarification: The theoretical sum of the interior angles of a traverse should equal to (2N-4) right angles, and that of the exterior angles should equal to (2N+4) right angles, where N is the number of sides of a closed traverse.
