<P> Plane surveying assumes the earth is flat . Curvature and spheroidal shape of the earth is neglected . In this type of surveying all triangles formed by joining survey lines are considered as plane triangles . It is employed for small survey works where errors due to the earth 's shape are too small to matter . </P>
