I need a function that will take a set of coordinates (latitude and longitude) and calculate the magnetic declination (also known as magnetic variation) for those set of coordinates taking into account the changing nature of teh field. I have the C source for it but don't have the time to port it over to ASP right now.
Hi, I can developed the asp function to calculate magnetic declination. I understand the c file and I can convert to asp easily. I guarantee a fast work. Greetings.
