Location-based critical infrastructure interdependency (LBCII) [electronic resource] / Rifaat M. Abdalla, Keith K. Niall. Toronto : Defence research and Development Canada, 2010. 1 v. (various pagings) : maps, figs. Technical report ; 2009-130 "April 2010." Includes bibliographic references. This report presents the notion of Location-Based Critical Infrastructure Interdependency (LBCII), and the steps to identifying such interdependency. A scenario is simulated of a shallow 7.3 on the Modified Mercalli Intensity scale (MMI) subduction earthquake in the Strait of Georgia, British Coloumbia (at latitude 49.45 degrees and longitude 123.941 degrees). Spatial and functional interdependencies were shown in simulation. A total of twenty-three hydrostructures around Vancouver, British Coloumbia were found to be at risk. Potential damage was most severe to the north of Grant McConachie Way, on Sea Island near the Vancouver airport. The potential for building damage was assessed across ground acceleration zones. Three categories of building damage were identified: high risk, low risk, and safe. Spatial analysis helped identify levels of risk. These levels take into account population density in the building damage zones, and by identifying electrical failure as a consequence of an earthquake. It was possible to visualize the other effected critical infrastructure sectors. This report emphasizes visualization capabilities of (WebGIS) a web-based, geographic information system, and outlines strengths and weaknesses in the spatial models used for web visualization. Issues identified in the development of spatial models for LBCII are related to data access, input and processing requirements.
