【 摘 要 】

Playing role as coastal shield with enormous economic value and ecological functions, mangrove forest management is always challenging to be studied. As either the largest archipelagic countryor the largest mangrove forest habitat around the globe, Indonesia needs a national mangrove forest baseline data and its updating for coastal management. Many stakeholders and institutions, including Geospatial Information Agency (BIG), had conducted mangrove mapping and updating. However, in order to achieve one mangrove national data, coordination and synergy among stakeholders and institutions such as: the Ministry of Environment and Forestry as mangrove custodian, Indonesian National Institute of Aeronautics and Space, Ministry of Marine and Fisheries, and BIG aligned with the National Mangrove Working Group is needed. A fundamental step for national mangrove forest management is the establishment of National One Map Mangrove Program by means of coordination, synchronization, and integration of mangrove geospatial data from various stakeholders. This paper will discuss the technical process of data integration and field survey in order to produce One Map Mangrove Sulawesi with the same geo-reference, database, and also standard and specification. The result of One Map Mangrove Sulawesi Program comprises of information about mangrove current status, existing area, and its distribution in Sulawesi.Beside the geospatial data from Ministry of Environment and Forestry and other institutions, the primary data used to map mangrove forest in Sulawesi is SPOT 6 and SPOT 7(year 2014 - 2015) imageries yielded map scale of 1: 25,000. On screen digitation using NIR, Red and Green bands and Normalized Difference Vegetation Index (NDVI)image transformation are applied for the initial canopy density classification. Field survey was doneto obtain field data forvegetation analysis, image classification andre-interpretation. In 2015, the process of producing One Map Mangrove Sulawesi has been carried out. It was preceded by compiling geospatial data from BIG and other stakeholders. The integration process is based on national technical guidelines for mangrove mapping. Ground check also done by the One Map Mangrove team to ensure theaccuracy and novelty of data. The result shows that SulawesiTenggara has the largest mangrove forest area, it is 62,446.4 ha, with a crown density dominance in rare class. This paper illustrating the process of One Map Mangrove Sulawesi, where data from the local stakeholders are accommodated properly.
