23. UsingParticipatoryMappingwithStudents,CitizensandWardOffices
KeyAdvantages
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 officials with community

24. ParticipatoryMapping
KeyChallenges
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
