Crowdsourcing in Dar es Salaam: Ramani HuriaRamani Huria

2011 Pilot in Tandale showed that Student and Citizen can be a source of Useful DataHow we Started

Collect very Local Data – eg. drain type, business types, etc

Fast changing features – eg. rubbish sites, flooding areas

Citizen can voice Issues on the map – eg. children play areas

Participatory MappingKey Challenges

Coordination: Mix of Universities, COSTECH, City and Disaster Management Department UAV

Permits: require Ministry of Defense, Lands and Survey, Aviation Authority

Data Processing: flying is easy, processing takes trial and error for good outputs

Community Mapping: low cost but labour intensive – relies on steady supply of students

Policy and legislation for government use of citizen generated open data

Outreach to policy/decision makers on how ‘maps’ can provide efficiency

Optimize local and international communities with new forms data and methods
