When a pocket query is executed based on distance (say... 25 miles from a point) which method of distance is used, the Pythagorean theorem method or the great circle calculation?

 

Also, does anyone know the algorithm for converting from DD MM.SSS to UTM ?

I really like Fizzymagic's little GeoCalc program. No installation necessary - Just download it and run it. I converts the various types of coordinates and does distance and projection calculations too. RM

No, I'm writing a program that figures out specific things. So I need to know HOW to do it rather than have a program than does it for me.

Did you read RobertLipe's link? It contains the formulas you need.
