There are two scales in the viewfinder: a percent slope scale on the right margin and a slope angle scale on the left margin. This point should be: Make sure point A is at the top,
Vertical angle is the angle between horizontal distance and slope distance. slope Distance is the length of slope from bottom to the top of the slope. When you look through the sighting device of the clinometer,
Continuing with the example of a slope percentage of 6 and a rise of 25, the equation will look like this: run x 6 = [(25/run) x 100)] x run.

There are two groups of methods for determining slopes. 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. Look over the equation for calculating horizontal distance, which is slope = rise/run x 100. Calculate horizontal distance from slope distance and zenith. .3R. eyes and sight at that point instead. Multiply each side of the equation by the 'run' variable. 9. The equation for determining the slope between 2 points is: Slope or m = (Y 2 -Y 1) (X 2 -X 1) As stated above, point 'a' has the values of x 1 = 1 and y 1 = 2 and point 'b' has the values of x 2 = 5 and y 2 = 4. In trigonometric leveling from point A to point B, the slope distance and zenith angle measured at A were 2504.897 m and . to the board's longer edge.

Vertical angles are measured in the vertical plane either above or below the horizontal plane of the instrument. in order to find the t, 8. You can make a simple plumb-line from: 7. 7. slope you are measuring, expressed in. The equation then becomes h = Tan A x d . 13. To measure uphill slopes, the plumb-line should be at the edge of

Aim the board at a mark which you have aligned at eye level. This reference is for calculating the horizontal distance between two geographic points at difference elevations and is based on the mathematical relationship between the sides of a right triangle. If your horizontal distance is in miles, you need to convert to feet; if the horizontal distance is in kilometers, you'll have to convert to meters. Horizontal distance traveled can be expressed as x = Vx * t , where t is the time. The slope distance between the two points is 24.776 meters and the zenith angle is 81 17'. h = (x2+ y2) In the equation above, y2 - y1 = y, or vertical change, while x2 - x1 = x, or horizontal change, as shown in the graph provided.
