What is horizontal distance in surveying

In plane surveying, the distance between two points means the horizontal distance. If the points are at different elevations, then the distance is the horizontal length between plumb lines at the points.

What is horizontal distance?

Horizontal distance means the distance on a line parallel to the horizon (not parallel to the slope). Sample 1. Save. Copy. Horizontal distance means the distance between two points measured at a zero percent slope.

How do you find horizontal distance?

Horizontal distance can be expressed as x = V * t . Vertical distance from the ground is described by the formula y = – g * t² / 2 , where g is the gravity acceleration and h is an elevation.

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.
