Thanks for the excellent GpsTools product. I mostly use it for conversions between different datum/grid systems. I am already a registered user.
I am new in the area and I have an urgent question:
I just started developing a fleet management software that, until now, has been intended for Greece and the GGRS87 Grid worked perfectly.
From now on, the software should be able to work on a paneuropean basis. Obviously, the GGRS87 Grid is no more accurate (shifts eastings or northings while in other countries).
Thus, I need a new Grid system that covers the whole Europe. Due to the nature of the calculations in the software, it should remain two dimensional (UTM_NORTH that additionally uses the zone would pose severe changes in the business logic). Moreover, I need to be able to calculate distances using pythagorean theorem for distances in different countries like I did using the Greek Grid System until now.
What kind of solution would you recommend for my problem?
Any answer is welcome and highly appreciated, thanks in advance!
