WebDifferential leveling (Point having an obstacle in between ) fig-3. 1.3. Reciprocal Leveling. It is the operation of leveling where the difference in elevation between two points is accurately determined by two sets of reciprocal observations.. This method is very useful when the instrument cannot be set up between the two points because of an obstruction … WebDOUBLE - RODDED LEVELING: The figure shows a schematic arrangement of a differential level route employing two rods. The values indicated represent backsight and foresight readings taken on two sets of turning points. Prepare and complete the differential level notes for the information shown and perform the customary arithmetic check.

WebDouble rodded leveling. it is the establishment of differences in elevation between two or more points by employing two level routes simultaneously. Profile leveling. Differences … WebCross-section leveling is usually done with a hand level after the profile run has been made. The method is as follows: From the profile run, you know the center-line elevation at each station. Suppose you want to take cross-section elevations at 10 ft intervals for 40 ft on either side of the center line. The first thing you do is to determine ... WebDIFFERENTIAL LEVELING WITH TURNING POINTS (DOUBLE RODED) Turning Point (TP) An intervening point between BMs or TBMs upon which a backsight and a foresight are taken. Backsight (BS) A rod reading taken by "looking back" at a point of known elevation such as a BM or TP. Foresight (FS) A rod reading taken when "looking ahead" at a point … kian tulk motorcycle accident
