Priority Mapper Priority Mapper is an extension of ESRI’s ArcMap, which integrates priority analysis with geographical information systems (GIS). It is targeted at managers and executives to realistically prioritize actions related to geographically distributed assets and resources. The output is in the form of visual representations of the prioritizations and recommended alternatives. The target operating platform is Windows. Due to a bug in Microsoft’s installer for SQL, the beta launch of Priority Mapper was delayed.
