By: Haseeb Jamal On: How To, Notes. Advantages of triangles: This is simple and rapid. For ordinary engineering work and site surveys, a precision in the rangeintoinis normally required for horizontal control and the notes in The lexical definition of triangulation is that it is a process of using trigonometry in determining an unknown point or location by using the position of two fixed points a known distance apart ( ster’s New Collegiate Dictionary,). Triangulation work is carried out in following step. Reda FekryDetermine the level of point B, where the level of A = m and the horizontal distance between A and B =m, the zenith angle = º, the height of the instrument at A = m, and the height of signal at B = mThe slope distance and Triangulation is a method used to increase the credibility and validity of research findingsCredibility refers to trustworthiness and how believable a study is; validity is concerned with the extent to which a study accurately reflects or evaluates the concept or ideas being investigatedTriangulation, by combining theories, methods or observers in a research Triangulation surveys are carried outto establish accurate control for plane and geodetic surveys covering large areas,to establish accurate control for photogrammetric surveys for large areas,to assist in the determination of the size and shape of the earth,to determine accurate locations for setting out of civil engineering wo Triangulation surveying is the tracing and measurement of a series or network of triangles to determine distances and relative positions of points spread over an area, by measuring the length of one side of each triangle and deducing its angles and length of other two sides by observation from this baseline G PULLAIAH COLLEGE OF ENGINEERING & TECHNOLOGY guide to triangulation classification and associated precisions, the precision ofa survey being linked to the field methods and type ofequipment used. Economical method 6, · TRIGONOMETRIC LEVELING –NUMERICAL EXERCISEGeodesyDr. Erection of Signals & TrianglesA chain of triangles is very rapid and economical when a narrow strip of terrain is to be surveyedAngles less thano or more than o are not permittedFor well-conditioned triangles, angles should not be less thano or more than o. The triangulation metaphor used in research was derived from construction, surveying, and navigation at sea Triangulation surveying is the tracing and measurement of a series or network of triangles to determine distances and relative positions of points spread over an area, by How to do Triangulation Survey.
