There are 360 meridians on our planet and we are going to cross them all.
If you wish you can be part of our journey and support us with your own personal "meridian". Choose your favourite meridian and we will send you a certificate from the place where we have crossed it. Don't forget to mention your chosen meridian.
Meridians from 0 to -180 (west) and from 0 to +179 (east)
