The database is structured into 5 main groups of data covering: basic geography, soil and land use/ cover, coastline, human activities, and pollution data. There is a further subdivision over 45 data layers covering issues that range from protected areas and green spaces, over transport infrastructure to basic relief geographical data. Two aspects of the use of this database are discussed in more detail: (a) land use changes during the period 1988-1998. The results of this analysis show to which extent urbanization took place in the Ha Long area. (b) coastal line changes which are induced by both natural and human activities. During the period 1988-1998 in the wider Ha Long bay area 894 ha of water and 124 ha of mangroves were converted into development land.
