MANGROVE EXTRACTION IN GLORIA, ORIENTAL MINDORO USING LIDAR

摘要

Determining the spatial location of mangroves is important in environmental management of coastal ecosystems. Mangroves serve as protection of shorelines from storms and waves. Various fauna thrive on mangroves; it serves as nursery for shrimps, crustaceans, mollusks and fishes. Through remote sensing and geographic information system, the environmental managers will be able to conduct a rapid and effective assessment that can be used as basis for habitat management plans. Light Detection and Ranging (LiDAR), a remote sensing technology that can examine the surface of the earth, has the capacity to produce high accuracy and high spatial resolution map. This study aims to determine the location of mangroves in Gloria using LiDAR and to propose a rehabilitation site for mangrove plantation in the area. There are histories of storm surge and strong typhoons in Gloria that affect several households in coastal zone. An additional layer of mangroves can serve as a protection for these threats and can lower the vulnerability of Gloria in such disasters. This study used support vector machine in extracting mangroves guided by field survey data. The produced map clearly shows areas that lack layers of mangroves; abandoned fishponds were also classified and these are the proposed priority areas for rehabilitation.
