ABSTRACT: The decreasing financial resources of many Styrian municipalities, particularly the small ones, lead policy makers to rethink funding allocations. Policy makers considered the inter-municipal use of public utility providers as well as the creation of regional authorities. These arrangements should provide for a more efficient and cost reduced usage of public utitlity providers. Due to these facts, the division 16 of the provincial government in Styria launched the project “Modelling the coverage of public utility providers”. Within the scope of the project an ArcGIS Plugin was developed for modelling the coverage as well as for modelling the degree of capacity utilization of public utility providers in Styria. The results of the analysis provide transparent information about an optimized spatial distribution of public utility providers which creates the base planning criteria for the intended inter-municipal use of these facilities.
