Since the beginning of the modern American Intelligence Community apparatus, the need to understand how people communicate via their media has been important. The need to locate television and radio infrastructure and the extent of effects have been required in government to learn about the understandings, feelings, and values of other cultures to support clear and thoughtful communication with other nations. The Open Source Center (OSC) within the Office of the Director of National Intelligence has monitored global media sources for almost seventy years, and recently has begun to locate and analyze the geographic extent and effects of these sources. This report describes the creation of a prototype geographic information system which models the television and radio broadcast system infrastructure and broadcast areas of OSC sources. The project reviewed the social and interactive processes of media to learn about the spatial relationships between objects such as stations, towers, broadcast transmitters, and owners within the broadcasting system. The project prototyped a GIS which modeled these features and relationships in a ESRI-based geodatabase. The prototype utilized the ArcGIS suite of tools from ESRI to perform database management, analysis, and to implement Web-based Open Source Consortium Web services. The resulting prototype GIS provided OSC a platform which it could learn from and later implement.
