This process is known as surveying.
The father of surveying is widely considered to be Thales of Miletus, an ancient Greek philosopher who lived around 600 BCE. Thales was known for his contributions to various fields, including mathematics, astronomy, and geometry, which laid the foundation for modern surveying techniques.

Plain Surveying Geodetical Surveying
In surveying, backsight refers to sighting a previously established point in order to orient the instrument before taking new measurements. This helps ensure accuracy and consistency in surveying work by referencing known points.
The main classes of surveying are geodetic surveying, topographic surveying, cadastral surveying, construction surveying, and hydrographic surveying. Geodetic surveying deals with large areas and high accuracy measurements for mapping the Earth's surface. Topographic surveying focuses on determining the natural and man-made features of a specific area. Cadastral surveying involves demarcating property boundaries. Construction surveying is done to guide the construction of infrastructure and buildings, while hydrographic surveying is used to map underwater features.
General classifications of surveying include geodetic surveying, plane surveying, topographic surveying, cadastral surveying, construction surveying, and hydrographic surveying. Geodetic surveying deals with large-scale measurements of the earth's surface, while plane surveying focuses on small-scale measurements on a flat surface. Topographic surveying involves mapping of the land's natural features, cadastral surveying deals with land parcel boundaries, construction surveying is used for building projects, and hydrographic surveying is for mapping bodies of water and their features.
