Calculate the height of an object from a baseline when its projected position to the ground is inaccessible. Case scenario when baseline AB is level and collinear with object.

Calculate the height of a building where the ground is sloping up or down from the observer.

Calculate the height of a building by observing its top from two ground points and measuring corresponding vertical angles.

Re-establish the reference station T (inaccessible by the surveyor) onto position B and calculate the coordinates of stations A and B.

Re-establish the reference station T (accessible by the surveyor) onto position B and calculate the coordinates of stations A and B.

How to implement on the ground the main components (start, middle, end points) of a circular curve with known radius R, tangent to two main alignments E1 and E2, where node K (intersecting point of the two main tangents) is not accessible to occupy.

How to implement on the ground the main components (start, middle, end points) of a circular curve with known radius R, tangent to two main alignments E1 and E2, by occupying node K (intersecting point of the two main tangents).

Determine the length between two points A and B by measuring two side lengths from a third occupied point C and the included angle c. Points A and B are visible from point C, but interrupted between each other.

Calculate the volume included between a horizontal plane, a ramp (inclination 1:m, side slopes 1:n) and a vertical wall using Simpson’s rule.

Calculate the coordinates of a known point P in an orthogonal coordinate system to a reference orthogonal coordinate system preserving shapes (angles) during transformation, in 2-D space.
