Fujitsu Limited and PT. Fujitsu Indonesia today announced they have built an augmented reality (AR)-based river information system to monitor water levels for the city of Manado, North Sulawesi, Indonesia, as part of an effort to prevent flood disaster in the area.

From February 23 to March 18, the institutions have been conducting a field trial to evaluate its usability and effectiveness.

The new system is a mobile app that observers and can measure water levels, take photos, and add information on conditions in their surrounding areas. Observers use smartphone cameras to read AR markers placed in the river basin. The app then displays a scale superimposed on the image of the river, and just by tapping the water’s on-screen surface, they can digitally measure water level.

The system was built at the request of the Japan International Cooperation Agency (JICA) Indonesia Office, and the North Sulawesi province River Basin Organisation Sulawesi I, Ministry of Public Works and Housing (PU-PERA BWS Sulawesi I).

The data is accumulated and consolidated in a Fujitsu data center, with water level changes at multiple measurement locations can be visualised in graphs and plotted on a map.

The system was jointly built by Fujitsu and Fujitsu Indonesia, leveraging the brand’s expertise and experience from developing river information systems in Japan.

Sea-facing Manado is located at one of the northernmost province in Indonesia. The city has four medium-sized rivers flowing through it and is vulnerable to large disasters such as the large-scale flooding in January 2014 which claimed a number of lives.

Monitoring of river water levels, followed by rapid sharing of information by government workers when water levels reach alarming levels, and speedy evacuation instructions, will help to prevent greater casualties in the future.

The JICA Indonesia Office believes the smartphone-based app will help provide a sustainable solution with a low operating cost and convenience.
