I became involved in mapping in 2015 when i joined with my fellow youth mapper in HOT. We Mapped some wards in Dar es salaam like Vingunguti , Mwananyamara, Hanannasif and Mzimuni ward on which we mapped some featured like Drainage features, roads, building features also those areas which are vulnerable for floods . Tools which where used were like GPS, JOSM software, Also there were involvement of community members in order to create awareness in the community about mapping. It was very interesting exercise .
