Calculate the height of an object from a baseline when its top and bottom is visible but not accessible from observation points. Case scenario when baseline AB is horizontal and in line with object.

Calculate the height of an object from a baseline when its projected position to the ground is inaccessible. Case scenario when baseline AB on sloping ground and not in line with object.

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

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 but not in line with object.

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.
