Basing on existing disaster data, the Program identified the most flood-prone and high-risk areas in the country to come up with an initial listing of 17* target critical river basins. Other priority areas, such as Infanta and Lucena, and cognate systems, like Iponan and Mandulog, were added to the list in the course of the implementation of the Program. With Phil-LiDAR 1, coverage was extended to include additional major river basins in the Philippines.
*LiDAR data used for the generation of the Marikina-Pasig flood hazard map was obtained from the GMMA-RAP Project
All datasets can be accessed in the Program's data portal, LiPAD.
