Trigonometric leveling is so named because it uses a total station instrument's (TSI) slope distance and zenith angle measurements to mathematically compute an elevation difference which, with a few more bits of information, can be used to determine a point's elevation. How do you find horizontal distance with angle of depression? Levelling devices help you measure the difference in levels What is the fluid speed in a fire hose with a 9.00 cm diameter carrying 80.0 l of water per second? To calculate percent slope, both rise and run must be in the same units(for example, feet or meters). This will be your sighting To successfully calculate the horizontal distance, which is also known as the run, between two points, you need to know the vertical distance, or rise, between the two elevations and the percentage of slope at the beginning of the horizontal elevation to the top of the vertical elevation. Although I haven't yet purchased This app plus still it is very helpful, if I could give it 100 stars, I would, not just the answers. the sighting pole. Lets assume that the slope distance, s, from stations A to B (corrected for meteorological conditions and EDM system constants) is 2,762.55 feet. 7.
