Quadrangles and Areas on Spheroids

Find areas bounded by meridians or parallels, find quadrangles surrounding points

A quadrangle is a polygon that is bounded by two meridians and two parallels. Use these functions to calculate surface areas of polygons on spheroids and to find quadrangles surrounding points, lines, and polygons.
