Plane surveying is the correct answer because it is based on the assumption that the Earth is flat over small areas, allowing for simplified calculations and measurements. This method is generally used for projects covering limited distances where the curvature of the Earth can be ignored without significantly affecting the accuracy of the data collected.

In contrast, geodetic surveying accounts for the Earth's curvature and is necessary for large-scale projects because it provides a more accurate representation of the Earth's surface. Control surveying is a fundamental method that establishes reference points and relies on both plane and geodetic techniques, depending on the scale. Cadastral surveying involves the boundary measurement of land parcels and may utilize either plane or geodetic principles, depending on the area and legal requirements.

Thus, plane surveying uniquely negates the effect of the Earth's curvature, making it the appropriate choice in this context.
