The Philippines: Department of Science and Technology (DOST) and University of the Philippines are conducting an aerial survey for the production of a 3D map that would identity flood and other natural hazard-prone areas.
The development of 3D map is a part of Philippine Information Agency’s project NOAH (Nationwide Operational Assessment of Hazards), the country’s flagship programme in disaster mitigation. The survey is being conducted under the Disaster Risk and Exposure Assessment for Mitigation (DREAM) programme which aims to develop accurate flood hazard models to identify areas most at risk to flood and other natural hazards. By employing the LiDAR technology, 3D datasets will be created to be used as basis for reliable, detailed and up-to-date flood hazard models for the country’s 18 major river basins and watersheds, and subsequently, for all flood-beleaguered areas in the country. 3D mapping could also be useful in the other areas such as forest inventory, environmental monitoring, infrastructure planning, archeological surveys and agricultural assessment etc.
