OpenStreetMap and crowdsourced mapping projects such as Crowd2Map, Data Zetu and Ramani Huria can help empower rural communities in Tanzania to put themselves on the map and contribute towards their development.

GROWING LOCAL MAPPING COMMUNITIES IN
RURAL TANZANIA TO AID DEVELOPMENT

2. WE’RE MAPPING RURAL TANZANIA. WHY?
• Remote villages are EXTREMELY poorly
mapped.
• Local officials lack maps of their area.
• This makes navigation and planning
difficult.
• We are mapping onto OpenStreetMap
that is accessible to everyone online and
on phones, and to print paper maps.

3. WE’RE MAPPING RURAL TANZANIA. WHY?
• Much of rural Tanzania is blank in Google Maps and OpenStreetMap.
