There is no longer any possibility of monetary to us in this problem. It was just a problem my boss described to me that I found interesting and thought might have an elegant solution. There is no application for spherical trigonometry in our present positions. ----- Original Message ----- From: "Fred lunnon" <fred.lunnon@gmail.com> To: "math-fun" <math-fun@mailman.xmission.com> Sent: Wednesday, February 09, 2011 1:02 AM Subject: Re: [math-fun] Spherical trig question

... Just recently, my new boss told me he had worked at a mapping company, and one of his last tasks, which he did not finish, was to compute the area of a map region (spherical polygon) with vertices given in lat-long coordinates. I was trying to apply the same technique, projecting the edges down to the equator and adding the areas of the quadrilaterals thus formed, hoping that this area might have some tractable formula in terms of the lat-longs. ...
