Our past collaborations

NGO Collaborations

We'd like to say a huge thanks to all non-governmental organizations for reaching out, asking about the use of our work. The fact that they find our maps fitting to illustrate the important issues they fight for really means a lot to us.

These non-profit organizations are usually doing their work on a limited (or sometimes non-existent) budget, so we are more than happy to let go of the licensing fee to help their cause. We really hope our work can help raise awareness and deliver their messages all around the world. If you are working on a similar project or would like to use our maps for educational purposes, please feel free to contact us so we can discuss the details.
