UNEP-GEMS/water programme - water quality data, GEMStat and open web services - and Japanese cooperation

The purpose of this paper is threefold. First, it demonstrates how monitoring stations that collect water quality data can be situated globally via satellite data from Google Earth. Important technical issues such as interoperability and Open Web Services are discussed in this context. Second, it illustrates how researchers at local levels can benefit from this global technology. The discussion draws from the online water quality database, GEMStat, which contains water quality data and sediment load calculations from around the world. These types of data, collected locally, can be shown to bear global implications through Internet technology. GEMStat has been expanded to include Open Web Services to enable interoperability with other online databases. Third, it illustrate an international framework of cooperation through GEMS[Water Japan, introducing onsite monitoring activities as well as management of international river basin (Mekong La Plata). Considerations for future application framework are presented in conclusion. Copyright (c) 2007 John Wiley & Sons, Ltd.
