The mangrove ecosystem develops as the forests sites at the upper half of the tidal zone. This means that the forest systems may have a mitigation role of sea impacts and the habitat may suffer the negative impact such as the habitat degradation by the sea-level rise. The forest ecosystems might be has the double role.

Under such circumstances, accumulation of the scientific knowledge for concrete evaluation of the coast protection function by a mangrove ecosystem serves as pressing need. Mapping for grasping the actual distribution and condition of a mangrove concretely is indispensable infrastructure improvement.
In our team, maintenance of map information is promoted as the foundation for grasping quantitatively the effect of the climate change adaptation measure which a mangrove ecosystem has. The mangrove habitat distribution traced and transfer to polygon in 1/25000 scale from World Imagery of ArcGIS. The environmental relations such as landform, land use, land cover, tide, ocean-current data also are compiling by 0.5 degree grid.
