Only linear measurements are made i a) List all the survey lines of traverse and its lengths b) List all traverse stations and included angles measured at each of them c) Adjust the included angles to satisfy the geometrical conditions d) With the bearing of one traverse line known, determine the bearings of all other survey lines e) Compute Latitude & Departure of all survey This document provides information about an engineering survey fieldwork conducted using a theodolite. Multiple rounds of measurements should be taken and averaged to achieve desired precision. 6. Roman surveyors, known as "gromatici," used various instruments, including the groma (a cross-shaped instrument) and the dioptra (a surveying tool similar to a theodolite), to Surveyor – Semester 2 Module 2: Theodolite Survey Reviewed and updated on: 01st November 2019 Version 1. 3 ADJUSTMENTS 1. Oct 23, 2023 · THEODOLITE SURVEYING CLASSIFICATION OF THEODOLITES A. This type of general theodolite is also termed as direct reading theodolite. RCI4C001 SURVEYING Module IV Theodolite Survey: Use of theodolite, temporary adjustment, measuring horizontal andvertical angles, theodolite traversing THEODOLITE SURVEY 1 Mr. A theodolite traverse is a survey technique where a series of lines on the earth's surface are measured for their lengths, bearings, horizontal angles, and vertical angles. Mahmoud M. 7. This allows forming simultaneous equations that can be solved for K and C. It explains how to set up a theodolite, measure horizontal and vertical angles using different techniques, and record field data. The formula used: P = The methods. temporary and permanent. Upon adjusting the leg, the bubble will either move into the circle (the instrument is level), or it will slide around until it is exactly opposite May 8, 2015 · 2. Refer to Fig. 3140601 Surveying Module 2 Theodolite Traverse - Free download as PDF File (. Uses of Tachometry Question Type 2076by Kmt - Free download as PDF File (. Fig. It introduces different types of surveying including chain, compass, plane table, theodolite, and tacheometric surveying. The key parts of a transit theodolite are identified as the leveling head, lower circular plate, upper plate, plate levels, compass, diaphragm, T-frame, plumb bob, tripod stand, and telescope. 3. If the plan is bounded by straight boundaries, it can be tackle by subdividing the total area into simple geometrical shapes, like triangle, rectangle, trapezoidal etc… and the area of the figure are computed from the dimensions. The 12-day camp involved topographical surveying of sites for Nepal Electricity Authority and a bridge site in Roshi Khola, Panauti. Theodolite Traversing Numericals – Useful Formula a.
