Abstract

A system and method that determines risk exposure for a selected site by using adjacency analysis to identify and process sites that may not be visible to the user on a display unit. The system determines the risk exposure for a selected site by using geographical adjacency to evaluate other sites for potential impact. The system geographically stores hazard sites and sensitive receptor sites. Moreover, the system creates and stores a sphere of influence and a sphere of receptivity for each hazard site and sensitive receptor site, respectively. For the selected site, the system calculates a sphere of evaluation based on a geographical location of the selected site and a given radial extent. The system determines if the sphere of influence or the sphere of receptivity intersects the sphere of evaluation and outputs the results of the intersection analysis to the display unit. The system analyzes sites that are external to the view area by examining spatial relationships between the selected site and said hazard sites. As such, all potential impact sites are not required to be visible to the user. The viewable area of the display unit is automatically reconfigured to include the farthest evaluated site.
