My engagement with OpenStreetMap began through my involvement as a YouthMappers volunteer, where I developed a strong interest in the power of open geospatial data for development and humanitarian action.

Calvin Amevienku is my name, a YouthMappers volunteer regional ambassador to Ghana. I have had the opportunity to support and connect student chapters, promote mapping activities, and encourage youth participation in open mapping across my region and beyond. This role has deepened my understanding of how collaborative mapping contributes to capacity building, digital transformation and community resilience.

Through my continued involvement with the Humanitarian OpenStreetMap Team (HOT), I have contributed to humanitarian mapping efforts that support data availability for underserved communities and crisis response. These experiences have strengthened my appreciation for the role of volunteers in building and maintaining high-quality open geographic data.

Being nominated as a 2026 HOT Voting Member is both an honour and a responsibility that aligns closely with my work as a YouthMappers Regional Ambassador. It represents a transition from active contribution to meaningful participation in governance and decision-making within the HOT community.

If selected, I aim to represent the perspectives of YouthMappers and regional contributors, particularly from Africa, ensuring their voices are reflected in HOT’s decisions. I am especially interested in strengthening youth engagement, supporting local chapters, and advancing capacity building initiatives that sustain long-term participation in open mapping.

I am committed to contributing constructively to HOT’s governance processes and to strengthening collaboration among HOT, YouthMappers, and local mapping communities worldwide.

Cheers!







I recently discovered this. You can survey for Open Street Map easy if you use your camera with location tags turned on. Take lots of pictures of anything that could be added or updated while you shop, walk or drive. Then later you can go through your pictures and use the location to find where they were taken. Compare the location tag against satellite images, and add everything you find useful in your photos.

I recently went on a trip and I’m adding businesses, addresses, stop signs, speed limits to OSM this way and its really helpful. Ive been able to add so much more details that I didn’t even know I saved in my photos. Try it!
