Surveying or land surveying is the technique, profession, art, and science of determining the terrestrial or three-dimensional positions of points and the distances and angles between them. A land surveying professional is called a land surveyor.
The data gathered from surveying helps establish planning and design and provides data that can be used to determine the best course of action. These can be as diverse as deciding the routes of major infrastructure projects, to planning a simple house extension.
