ONLINE MAPS IN GEOMED Internet Mapping, online GIS and their application in Collaborative Spatial Decision-Making

This paper gives an overview of Internet Mapping and discusses its use for Geographical Mediation. Internet Mapping summarizes a variety of tools, ranging from geodata and map servers up to online Geographic Information Systems (GIS). First, a classification is proposed, according to the services offered and to the techniques used. Then, the requirements of Collaborative Spatial Decision-Making (CSDM) for online maps are discussed in more detail with reference to the European Union research project "Geographical Mediation System" (GeoMed).
