2. Jakarta is located on a wide, flat alluvial plain on the
north coast of western Java. It covers 650 square
kilometers of land rises from five to 50 metres
above sea level.
40% of Jakarta, particularly the northern areas, is
below sea level, while the southern parts are
comparativelyhilly.
Thirteen major waterways flow through it and
empty intoJakarta Bay.
Rivers flow from the Puncak highlands to the south
of the city, across the city northwards towards the
Java Sea; the most important is the Ciliwung River,
which divides the city into the western and eastern
principalities. Other rivers include the
Pesanggrahan,and Sunter.
All these rivers, combined with the wet season
rains and insufficient drainage due to clogging,
make Jakarta prone to flooding.
Sometimes flood forces the people to evacuate so
that they need shelters.
In making decision for shelter location, the
government will overlay flood disaster historical
data and then with building data from OSM, e.g.:
Flood resistance, accessibility, Government
buildings
BACKGROUND
3. PROBLEMS
In dealing with this flood disaster, Jakarta provincial government developed Smart City platform
which involves public since it has an issue-reporting app known as Qlue and a flood map that
crowdsources citizen flood reports from Twitter, called PetaJakarta. The government needs to
input data from Qlue and Twitter and validate it. It would usually take a long time since the data
is not informative enough, e.g. no detailed location and no water level.
5. OBJECTIVES
1. Government
Ensure the input data from the public will be accurate enough
Reduce the time needed by the government to input data from the public to be validated by Kelurahan
Flood mapping in real-time
Make it easier to make decision, e.g.: shelter location, water pump location, pasukan oranye location.
2. Public
Make it easier for the public in mitigating flood disaster
Provide access of information to the public in real-time, e.g.: evacuation route, shelter location
