ILOILO CITY, July 22 (PIA6) - - The Department of Science and Technology 6 has already completed the Light Ranging and Detection Technology ((LiDAR) mapping of the three major river basins in Western Visayas including Iloilo City under its Disaster Risk Assessment, Exposure and Mitigation (DREAM) project.

The region’s three major river basins are Jalaur River Basin, Panay River Basin and Ilog-Hilabangan River in Negros Island.

DOST 6 Director Rowen Gelonga said a special LiDAR mapping was also conducted in Boracay Island.

 “For this year, we are continuing to map the rest of the Western Visayas region.We will cover Antique, parts of Negros Occidental and parts of Iloilo, so by the end of this year, practically, most of the floodplain areas of the region will be covered,” said Gelonga during a recent gathering of the members of Iloilo media in line with the July observance of the National Disaster Consciousness Month.

Project DREAM-LIDAR in partnership with the University of the Philippines seeks to produce up-to-date and detailed three-dimensional (3D) flood hazard maps for the flood-prone and major river systems in the country. It uses LiDAR, a state-of-the-art technology that could provide high resolution and detailed topographic hazard maps.

Gelonga said they will share with government agencies like Mines and Geosciences Bureau, National Economic Development Authority and the local government units the detailed hazard map, the final product of Project DREAM.

“Those high resolution maps will be the basis for the finalization of the Flood Forecasting Models which we are undertaking right now,” said Gelonga.

The flood models will be incorporated in the Project NOAH (Nationwide Operational Assessment for Hazards), a comprehensive site offering real weather picture of the country including data coming from the different PAGASA doppler radar stations in the country.

Aside from the website of Project NOAH at, Filipinos can also access online weather information through the various web-based weather monitoring and information system made available by DOST and partners on the following websites:;;; and

In a recent press release of the agency, DOST Secretary Mario Montejo said the best tool to prevent disaster is ensuring everyone’s safety by using all the information available to them and the lessons from experience in the past typhoons to prevent too much disaster loss. (JSC/LAF-PIA6)
