BanjirOnline Tweets is a crowd sourcing application that counts the amount of tweets on floods for 261 wards in Jakarta. During heavy rain, people can follow where floods have been reported. The user can:
- Follow the floods as observed by people tweeting about it
- Send their own flood report to the twitter account of the application
The application was validated and calibrated during six inundation events in 2013. The correlation between “floods” and “tweets on floods” proved very strong. After the next flood season of 2013/2014 the developers will release a new version calibrated on more events, with more detailed flood reports.
