Trigonometrical heighting is a process in geodetic surveying to determine the height of a point from mean sea level. This practical involves finding the vertical angle and slope distance of a line. It can be measured by using the total station. In geodetic surveying, there are three methods that can be used to determine height of a point.The methods are Single-ended trigonometrical heighting, Reciprocal trigonometrical heighting, and Simultaneous reciprocal trigonometrical heighting. All these three methods have their advantages and disadvantages. In our practical, we decided to use single-ended trigonometrical heighting. In this practical, we use single-ended trigonometrical heighting. In our triangulation practical, we have established four points on the ground. We also used the same point to carry out the trigonometrical heighting practical. We have been ordered to carry out this practical on the same site that we use in the triangulation & trilateration work. We need to choose a suitable method to carry out this trigonometrical heighting.
