Intersecting Spherical Polygons

I would like some code that finds the intersection of two spherical polygons. For simplicity, consider both polygons to be on the surface of earth -- which, also for simplicity, should be considered a perfect sphere.

The software input is two text files. Each text file contains a listing of coordinates of a single polygon.

Find the intersection of the two polygons and provide the result. The result will either be no intersection, a polygon, or multiple polygons. If the result is a polygon are multiple polyongs, create text files in the same format as the input.

No user interface is needed. You can make the text files have static names and always be in static locations (like c:[url removed, login to view]).

Some relevant information can be found online by googling &quot;intersecting spherical polygons&quot;. These sources may be useful for someone with a good engineering or mathematics background. Please do account for the spherical nature of the problem (the flat surface version of the problem is one I can already solve and program myself).

Any programming language can be used. Please ask if you have questions.

Regards,

jagusa

---INPUT FILE DETAILS---

Example Input

Explanation:

Each line is vertex of the polygon provides as: latitude, longitude(in decimal degrees; WGS84, if that matters). Note that the first and last coordinates close the polygon and, thus, are always the same; vertices are given clockwise. Positive latitudes value are the northern hemisphere (like 45 means 45 degrees North), negative latitudes are in the southern hemisphere (-12.5 would mean 12.5 degrees South). Also, positive longitudes are in the eastern hemisphere; negative are the western hemisphere. You can cut, past, then search for the individual coordinates in Google Local for clarification.
