  1. Scaling RamaniHuria Mussa Natty Technical Advisor Dar es Salaam Regional Commissioner’s Office

  2. 2011 Pilot in Tandale ward showed that Communities can be a source of Useful Data Collect very Local Data – e.g.. drain type, business types, etc Fast changing features – e.g.. rubbish sites, flooding areas Citizen can voice Issues on the map – e.g.. Solid waste dump sites

  3. 2011 Pilot in Tandaleward In September 2011, 25 Town Planning Students worked with 25 community members to map Tandale in 3 weeks August 2011 September 2011

  4. Advantages of Using Community Mapping Affordable Data Collection for local level – approx. $10,000 per ward Hyper-local details – trees, businesses, water points, facilities, drains Community Context – digitizing critical features for citizens Culture of participating in mapping strengthens relationship of ward office with community

  5. Pioneering New Technology Simple & Affordable UAVs – approx. $1,000 for phantom, $15,000 for ebee – low running costs High resolution – up to 3cm Basemap, 8cm Elevation model Timeliness – can choose exact day of mapping to suit project needs for baseline Cloud free – advantages over satellite and manned aircraft as drone fly under clouds Streetview mapping collects data of the streets, from the side

  6. Challenges to Scale RamaniHuria Coordination: Mix of Universities, COSTECH, City and Disaster Management Department. For UAV Permits we require Ministry of Defense, Lands and Survey, Aviation Authority Data Processing: flying UAVs is easy, but processing takes trial and error for good outputs with high spec computers – need to build this capacity in Dar es Salaam, we have the opportunity to lead Community Mapping: low cost but labour intensive – relies on steady supply of students and a willing community

  7. Towards Mapping All of our City • Map all 101 wards, we’ve mapped around 21 fully, drains in 41. We have far to go • Expand community resilience teams to all at-risk communities • Support community members in resolving challenges in their community • Build a center of excellence for mapping and flood resilience within the local universities – train the next generation of urban planners! • Expand training for city officials on how to make decisions with the maps • Make maps freely available and replaceable • Centralize production of our maps - reuse data making the maps, do not recreate and duplicate efforts • Make data open as much as possible, foster a culture of collaboration, between the Ministries, the City Council, Municipalities, Ward Offices and our community. Let’s build a smarter Dar es Salaam
