I was wondering if there is a way to calculate the Latitude and Longitude of a given point provided you know the range, azimuth, and elevation of said point?

This question came from our site for professional and enthusiast programmers.

Maybe but this is not the right site to ask the question. – Code Monkey Aug 16 '11 at 19:02

@Ram: I didn't downvote it. I voted to close. I am not the dictionary for StackExchange network so you can gladly go to The close reason only shows about 4 choices so I voted to close as off-topic. This has nothing to do with C# for starters and you are asking basically a geographical math question which has nothing to do with programming. But you can start next time by losing the piss poor attitude. – Code Monkey Aug 16 '11 at 19:06
@Dyppl - I appreciate the assistance. – Ramhound Aug 16 '11 at 19:11
@Ram: It has nothing to do with C# because there is nowhere in the question where you ask about C# (other than the tag which means nothing in this case). It should be tagged as algorithm. The 257 cases you cited had code or referenced a particular framework. You do neither. That's not the right way to ask a question around here. I can't migrate it so you will have to delete it. – Code Monkey Aug 16 '11 at 19:15

Please take a look at this link.

Taken off the page.

How do I get the Latitude, Longitude and height of the point indicated by Range, Azimuth, and Elevation?

use geoInitLocation() to establish a base location
use geoRae2Efg() to get earth centered coordinates
use geoEfg2Llh() to get Latitude, Longitude, and height.

This was exactly what I was looking for. – Ramhound Aug 16 '11 at 19:21
Glad I could help. Looks like some crazy crazy stuff. Would hate to try and write that in C#. Good luch with your project. – Jethro Aug 16 '11 at 19:25
I plan to attempt to PInvoke the dll. If I am able to determine how it works in more detail I will update my question. – Ramhound Aug 16 '11 at 19:43
