摘要：This paper is a review of the activity of the ISPRS WG IV/6 which aims to find better direction of thedevelopment of global database. There are some problems in developing global databases for mapping andmonitoring the environment. Though there are many projects or studies to develop global/continentalenvironmental variables such as IGBP, GLOBE, Global Mapping, AFRICOVER, G3OS, AARS, there is nocommon table to discuss barriers for the development of global /continental datasets/databases. In thispaper, these barriers are described. To cope with this situation, the WG started virtual workshop on theinternet which provides the opportunity to discuss these common problems. In addition to the virtualworkshop, the WG plans to have a real(physical) workshop in 1999, and plans to conclude the direction ofthe development of global database by the Amsterdam Congress in 2000. As one of problems, when wewant to use global environmental data, it is difficult to access it. Furthermore, it is sometimes difficult even toknow the existence of the data. To cope with this problem, the WG started to build metadata database ofglobal/continental environmental variables on the internet.
