Instruments for Surveying

Surveying is the practice that determines the relative three-dimensional positions of many different points on the earth’s surface. There are various instruments used in Surveying like Theodolites, Total station, Tripod stands, Plane table, etc. for measuring horizontal angle, vertical and sloping angle, which are very useful for giving accurate and precise measurement.

Question

1. Two points A andB are 1530m apart across a wide river. The
following reciprocal levels are taken with one level:
Readings on

In tacheometry survey, an intercept of 0.755m was recorded on a staff which was believed to vertical, and the vertical angle measured on the theodolite was +15º. Actually, the staff which was 4 metres long was 0.14m out of plumb bob and leaning backwards away from the instrument position. Assuming it was an anallatic instrument with a multiplying constant of 100, what would have been the error in the computed horizontal distance?
