A GIS was created to be used as general storage tool for most different activities. It started within the Man and Biosphere (MAB) program. The project was designed together with Esri-Germany. The beginning of the application of ArcInfo was sciences. This basic GIS evolved by adding a monitoring tool. Then GIS-based habitat analysis models came up. These models expand in complexity, and also jumps in scale are incorporated. All information is used for a GIS-based master plan and for traffic and leisure management.
