Mapping Fundamentals

Mapping Fundamentals

• The data collected through field surveying are presented in the form of a plan or a map.

• Since, the actual surface of the earth is curved, and the surface of the map is flat, a method of projection is usually used to fit a curved surface of earth into a plane surface of paper

• However, no map can represent a terrain without some distortion. To minimise the effect of distortion, conformal projections are generally employed.
