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 Tandale ward
In September 2011, 25 Town Planning Students worked with 25 community members to map Tandale in 3 weeks

4. When I was the City Director, I saw the power of this project from the early stages. I directed that we release the basemaps that we had to be open data. Now we have the Tanzania Open Data Program – but we here in Dar es Salaam were the first!

5. Now, from this foundation, as you have seen, it has scaled up
Now, from this foundation, as you have seen, it has scaled up! But we can scale it up further and make this useful project, even more useful to all in communities and local government

6. 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
Drainage Map
Transportation Map
Tandale Schools
Msasani Village

7. 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
We need to use different technologies to solve our problems. But also we need to build up our staff

8. Challenges to Scale Ramani Huria
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

9. 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
