Trigonometric Surveying

Trigonometric surveying is a method of measuring large distances and land features using principles of geometry and angles. Surveyors locate specific points by measuring angles from known reference points and calculating distances based on these angles, often with the help of instruments like theodolites or total stations. This technique allows for precise mapping of terrain, boundaries, and land contours over extensive areas without physically measuring every distance directly. It relies on trigonometry—using sine, cosine, and tangent functions—to determine positions accurately, making it essential for large-scale projects such as mapping, construction, and infrastructure development.
