The principle of tacheometric surveying is based on the property of an isosceles triangle i.e. the ratio of the distance of the base from the apex and the length of the base is always constant. The formula for the horizontal distance is determined using: H= K*s* cos ² θ Note: The additive constant is 0.00, and the multiplying constant is 100.00. WebTacheometry 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. This is done with the help of two special type …

WebSep 11, 2011 · The average vertical angles and the staff intercepts are substituted in the relevant expression for horizontal distance for inclined line of sight and vertically held staff and the horizontal distances of the staff stations A and B from the instrument station P are determined by the principles of stadia tacheometry. WebTacheometric surveying is a method of angular surveying in which the horizontal distance from the instrument to the staff stations are determined from instrumental observations only. Thus the chaining operations are eliminated. Field Work can be completed very rapidly Tacheometry is mainly used for preparing the contour plans of areas. raymond gifford

WebPrinciple of Tacheometry. The basic principle of Tacheometry is based on the basic principle of an isosceles triangle. On any two sides equal triangle means an isosceles triangle, there is one property that is used in the Tacheometry. Ratio of the perpendicular to vertex on their base and their base is always constant in isoceles triangle. WebA theodolite exercise was carried out and yielded the following information. The instrument was set up at point X. The reduced level at point X was 224. The height of the instrument was 1 and readings were taken to point D, E and F. Calculate the reduced levels of each point and the horizontal distance from each point to the instrument stations
