The purpose with the work is to study Fortums activities with hydro power plants, dams and reservoirs mainly in a premise jurisdictional perspective and to show how GIS would be a helpful tool for the future.

A great deal of the information that the Generation Hydro-division at Fortum are managing have a spatial element. That means that it is possible to spatially join this information to a geographical polygon, line or point. This information is today gathered from several different sources, such as files, paper maps and digital data of several kinds. A Geographic Information System (GIS), as and aid besides the ordinary tools should be an effective support in the everyday work with questions of a premise jurisdictional nature.

The goal of this work is to account for how to organize, present and analyse geographic information. We will show how to link from the map to traditional tools such as calculation- and register programs. Linking to documents of different formats and to pictures will also be demonstrated.

Gathered and processed data in different formats and from different sources will result in a GIS-application overlooking two separate control areas. For the lower parts of the river Ljusnan in the municipalities of Bollnäs and Söderhamn it will be accounted for the handling of hydro power plants. The other area includes the municipalities of Arvika and Eda in the county of Värmland, in which the handling of dams and reservoirs also will be incuded. In the attempt to give suggestions of different solutions the two areas diverge somewhat in the matter of drawing manners and scales.
