The Ministry of the Walloon Region is responsible for many geographical data, among which datasets of physical environment (geology, pedology, hydrology, etc.) dominate. In particular, the soil map is especially interesting because of its exhaustiveness, quality and precision. This dataset had been used early on in GIS applications (Decision-making Geo-Environmental Tool, Rural Areas Observatory) to provide help in solving point source pollution, protecting aquifers and soils, managing manure and sludge, etc. Geographical Reference databases including these datasets and various others (land use planning map, orthophotos, etc.) were published on the Intranet making up a distributed GIS. This infrastructure supports the administration's missions, including environmental permits, Common Agricultural Policy, rural development, Natura 2000, management of buildings and roads, etc. Meanwhile, this infrastructure is gradually becoming available through the Internet (geological map, topographical features, etc.) to form a geoportal (meeting interoperability requirements) for decision makers, citizens, scientists, engineering and consultancy companies, associations, etc.
