Calculate distance between two points on earth's surface given by latitude-longitude pair.

Description

Calculate distance between two points on earth's surface given by their latitude-longitude pair. Choose method 1 or 2. Method 1 uses plane approximation, only for points within several tens of kilometers; Method 2 calculates sphereic geodesic distance for points farther apart, but ignores flattening of the earth. Output is in km.

This looks like it could be a great program but as is, it doesn't do anything! In fact, I had to add a couple lines to the end to keep it from returning an error message. Please test your code before submitting it!

Appologize for the former one. That's imcomplete. A new version has been uploaded. This should be OK.

[David Terr]

That's much better! Keep up the good work.

Thanks. I was about to write the same function, but then I found it here: you made save some time! :)

line 36 should be

  method = 1;

instead of

  method == 1;

otherwise, very useful!
