Why Do We Need Astronomy in Land Surveying?

Various methods, sources, and techniques are used in land surveying Tulsa to provide the most accurate results possible. While some data is determined by technicians walking through a worksite (such as a boundary survey or topographical survey), others are determined through the triangulation of satellites (for example, a GPS survey). There is a very wide variety of surveying methods throughout the industry. Because some of these surveying methods take place at such a large scale, you may wonder if astronomy has a role in surveying.
