CALCULATING HORIZONTAL DISTANCE Divide both sides by slope percent. run = (rise × 100 ) / slope % is a measure of horizontal distance.

How do you find the horizontal measurement?
Look over the equation for calculating horizontal distance, which is slope = rise/run x 100. Plug your slope percentage and rise into the equation. For example, if you have a slope percentage of 6 and a rise of 25 feet, the equation would look like 6 = (25/run) x 100.
Why do surveyors measure horizontal distances?
Surveying and highway construction practice use horizontal distances rather than slope distances. This is necessary because the horizontal distance between two points does not change even if the ground is disturbed.
How do you measure horizontal distance from a total station?
When calculating the horizontal distance between points, this difference also needs to be taken into consideration. Because the total station gives a true slope distance, the horizontal difference is simply H = s * cos α (see figure below).
How do you calculate distance in surveying?
Early land surveyors measured distances based on the length of their equipment. For example, a chain consisted of 100 links, each measuring 0.66 feet in length for a total of 66 feet. Thus, to calculate a distance represented on a map in chains, you would have to multiply by 66 to get the number of feet.
