Thanks Phil, I understand the spherical issue. The biggest length I will be using is arround 60km, but on average arround 20Km. I haven't discussed, with my team, the precision issue, but as long has it stays within +- 200m I'd say it is ok. From you opinion do you think it is a reasonable error?
I also haven't decided if I will use the formulas that WALLY ATKINS kindly presented despite the fact that they are very interesting in deed. Could you please explain what you mean by: «watch of line that crosses the 180»? What is the 180?
