MuGIS multi-user geographical information system

Collaboration between users of a system is often a crucial factor for reaching given goals in an effective and efficient way. However, in many application domains, the current systems do not sufficiently support collaborative work (sometimes they even don't support it at all). One good example is geographical information systems (GIS), that usually only follow an one user at one time approach. In this paper, we present the development of a scalable Multi-user Geographical Information System (MuGIS). With MuGIS it is now possible to integrate large display environments with mobile smart devices for remote control. The system is deployed as a client-server architecture. It uses the NASA World Wind Java framework and SOAP web services for communication. On the client side, all common mobile smart devices are supported. The underlying concept provides different user roles and multi-user identification.
