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
