3. Do all fields of civil engineering need to use surveying? Explain your answers.

Yes

Explanation:

There are a few types of civil engineering surveys: plane surveying and geodetic surveying. In plane surveying, the surveyor treats the area as a level geometric plane, ignoring the curvature of the earth; this works best for a project that is less than 250 km2.

Geodetic surveying, on the other hand, considers the earth as a sphere. Surveyors use this category of survey only for very large projects. Most geodetic surveys are completed by government agencies for major infrastructure projects within their boundaries, such as canals and pipelines.
