For Jakarta Floodgate Monitoring, data is collected from all floodgates in the city in near real-time, complete with the status of each floodgate. The data used on the Jakarta Flood Map is the fastest and most accurate data because it comes directly from the DKI Jakarta Provincial Government, Dukcapil, BNPB, and other related government agencies. The portal includes a dashboard to monitor floodgates (Jakarta Floodgate Monitoring), display of flood-affected areas and flood level, list of public facilities affected by floods, story map about Jakarta floods, and the flood victims’ refugee area mapping. In response, the Jakarta Flood Map portal was created by the Emergency Spatial Support Center (ESSC), an initiative by Esri Indonesia. These conditions greatly hampered the effectiveness of emergency services and evacuation. The city’s transportation network was also disrupted, with the LRT (Light Rail Transit), busway, train, toll road, and airport effectively shut down. And for security reasons, power cuts were made in the most affected areas. The Ciliwung and Cisadane rivers overflowed and a number of floodgates were assigned emergency status.Ĥ8 casualties were reported due to landslides, hypothermia, electrocution, and drowning. Water levels reached highs of almost 15 inches – three times more than usual – due to the high rainfall intensity.
