Haw, R JMunchmeyer, F C2014-07-312014-07-3119831467-8659https://doi.org/10.1111/j.1467-8659.1983.tb00151.xA method is described for tracing geodesic curves across patched surfaces. Two techniques are discussed for constructing the curves - an initial value problem and a boundary value problem. Arc lengths are computed, as well as the enclosed area of an arbitrary region on the surface.10.1111/j.1467-8659.1983.tb00151.x225-232
