In surveying of differential leveling runs from BM10 to BM11 at a distance of 7.5km. It was observed that the leveling rod was inclined 6º from the vertical every time the backsight is taken. The average BS reading is 3.15m and the average length per set-up is 300m. Determine the error every 300-m set-up and the correct elevation of BM11 if the recorded elevation was 140.20m
A differential levelling was conducted from BM1 to BM2 30 km apart. BM1 is at elevation 124. 08 m. The backsight distances averages 150 m in length and the foresight distances averages 100 m. the recorded elevation of BM2 was 274.11 m. If the level used is out of adjustment such that when the bubble was centered the line of sight was inclined 0.003 m upward in distance of 100 m. What would be the corrected elevation of BM2?
In the two-peg test of a dummy level, the following observations are taken. *INserted Photo* Point M is equidistance from both A and B, while P is 2.50m away from B along the extension of line AB and 90 meters from B. Requirements: Determine the true difference in elevation between point A and B. Answer: ____________ With the level still set up at P, determine the rod reading on A and B to which the line of sight should be adjusted. Answer: ____________
tp has an elevation of 115.15 meters and the foresight taken at that point is 0.30 meters. if bs taken at bm is 1.42 meters. find the elev of bm.
Situation 1: A two-peg test is used to check whether the ine of sight of the level is in perfect adjustment and the following rod readings are taken, with instrument set up near A, backsight on A is 1.623 m. and foresight reading on B is 2.875 m. With the instrument set up near B, backsight on B is 1.622 and a foresight on A is 0.362 m. a. Find the difference in elevation. b. What should be the correct rod reading on A to give a level line of sight with instrument still set up near B? c. What should be the correct rod reading on B to give a level line of sight with instrument still set up near A?
A line of levels is run from BM1 to BM2, which is 12 km long. Elevation of BM1 was found out to be 100 m and that of BM2 is 125.382 m. Average backsight and foresight distance were 150 m and 100 m respectively. a) (Situation 1) If during the leveling process the line of sight is inclined downward by 0.004 m in a distance of 10 m, what would be the corrected elevation of BM2?
RECIPROCAL LEVELING. In reciprocal leveling across a deep ravine the following sets of rod readings were takent: Instr Near A: BS on A=1.719 m, Average Fs on B=2.578 m Instr Near B: Average BS on A=1.335 m, FS n B=2.176 m Point A is on one side of the ravine and has a known éle- vation of 197.428 m. Point B is on the other side. Deter- mine the elevation of point B.
For all the computed values with decimals, use four (4) digits after the decimal. Differential leveling runs from BM10 to BM11 at a distance of 7.5 km. It was observed that the leveling rod was inclined 6° from the vertical every time the backsight is taken. The average BS reading is 3.15m and the average length per set-up is 300m. Determine the error every 300m set-up and the correct elevation of BM11 if the recorded elevation was 173.20m.

A line of levels is run from BM1 to BM2, which is 12 km long. Elevation of BM1 was found out to be 100 m, and that of BM2 is 125.382 m. Average backsight and foresight distance were 150 m and 100 m, respectively. If during the leveling process, the line of sight is inclined downward by 0.004 m in a distance of 10 m, what would be the corrected elevation of BM2?
