How does the YouthMappers Validation Hub build maps and mappers?
summary
Validation Hub starts in 2019 and now supports a 371‑university network across 72 countries, running 193 YouthMappers projects while a cadre of 33 trained students has finished over 1,000 tasks and over 8,000 tasks validated. The Hub runs JOSM and HOT Tasking Manager workflows, seven intro, one advanced and six validation trainings, and piloted a project mentor pilot that assigns Hub mentors to 13–14 active projects to monitor edits via OSMCha, send screenshoted error guides, and mentor chapters through the full mapping lifecycle.
