What is a plane survey?

A plane survey refers to a surveying technique that assumes the Earth is flat and is typically suitable for relatively small areas where the curvature of the Earth can be ignored. This approach simplifies calculations and measurements, allowing surveyors to use basic geometric principles when determining distances and angles. When conducting a plane survey, the area covered is small enough that the effects of Earth's curvature are negligible, making it practical for tasks such as construction, land division, or property boundary delineation.

The focus on small areas is crucial because as the surveyed area increases, the Earth's curvature becomes more pronounced, requiring different surveying methods, such as geodetic surveying, which take into account the Earth's spherical shape. Understanding the limitations and appropriate applications of a plane survey is essential for accurate surveying practices.
