Spheroidal excess

Spheroidal excess

The amount by which the sum of the three angles of a spheroidal triangle exceeds 180^o. In geodesy, spherical angles are used instead of spheroidal angles; the difference between the two kinds of angles is quite small even for the largest triangles and is considered negligible for ordinary triangulation.
