What are 2 types of surveying?

Surveying is the process of measuring and mapping the land, and it is an important part of civil engineering and construction. There are two main types of surveying: geodetic surveying and plane surveying.

Geodetic surveying is the most accurate type of surveying and is used to measure large areas of land. It uses a variety of instruments, such as theodolites, total stations, and GPS receivers, to measure angles and distances. Geodetic surveying is used to measure the shape of the earth, create topographic maps, and measure the size and shape of large areas of land.

Plane surveying is used to measure smaller areas of land and is less accurate than geodetic surveying. It uses a variety of instruments, such as levels, transits, and tape measures, to measure angles and distances. Plane surveying is used to measure the size and shape of smaller areas of land, such as a building site or a road.

Both types of surveying are important for civil engineering and construction projects. Geodetic surveying is used to measure large areas of land, while plane surveying is used to measure smaller areas of land. Both types of surveying are used to measure angles and distances, and both are important for creating accurate maps and plans.
