Three GISCorps volunteers, Emmanuel Jolaiya from Nigeria, Sharon Omojah from Kenya, and Katarina Spasenovic from Italy have stepped up to meet the challenge of helping Crowd2Map Tanzania ( mentor new mappers and working to put Tanzania on the map. Crowd2Map attracts a great number of new mappers from all over the world to add data to OpenStreetMap. To help with data quality and training of new mappers, Crowd2Map Tanzania asked GISCorps to provide volunteers who were experienced mapping in OpenStreetMap using advanced editing tools and other open source GIS software.

Crowd2Map Tanzania is a crowdsourced mapping project set up by Tanzania Development Trust (, a volunteer-run UK charity established in 1975 to help grassroots projects in rural Tanzania. Crowd2Map aims to put rural Tanzania on the map. Since 2015, they have been adding schools, hospitals, roads, buildings and villages to OpenStreetMap, an open source map available to all, with the help of over 13,500 volunteers worldwide and 1500 on the ground in Tanzania.  With minimal budget and no staff, they have so far added over 4.2 million buildings. In 2017, they were awarded a microgrant by Humanitarian OpenStreetMap to train community mappers in 8 areas of Tanzania, and in 2018 they ran a mapathon as part of the UN general assembly in New York, sponsored by UNFPA.  They have also set up 8 different  Youthmappers Chapters in Tanzania (, and organised 2 Open Data Day events there, as well as the first State of the Map Tanzania.
