Defining interdependencies between various sectors of critical infrastructure has been a challenge for urban areas in terms of decision-making, especially in the event of an emergency. The URBAN-NET project has tied together over 30 data layers featuring nation-wide critical infrastructure in a relational database management system. These relationships are displayed on an interactive visual interface, enabling users to visually analyze complex interdisciplinary geospatial relationships. Recently, our graph has been refined by the addition of a radius feature, which limits the reach that one data layer may affect another by a distance determined by various sources found for each specific data layer. A service area polygon layer was also created for each distribution substation, in order to best simulate the area serviced by an individual substation in the event of a service disruption. These techniques help to refine our relational database results, making our geo-visual results more informative and accurate for users.
