Exploratory spatial data analysis to support maritime search and rescue planning

This study examined the use of exploratory spatial data analysis (ESDA) methods suitable for the analysis of point patterns to determine whether they would support maritime search and rescue resource allocation planning on the Pacific Coast of Canada. First the methods were applied to four marine incident data-subsets to determine whether they were technically feasible for use with maritime data and to provide a preliminary indication of their potential for planning. Second, the methods were applied in a series of problem-solving exercises suggested by Canadian Coast Guard Planning personnel to explore their utility for resolving 'real-life' planning issues.; In general the methods that provided graphic (rather than text-based) and local (rather than global) outcomes were the most useful. Despite several data-related challenges, the ESDA methods examined did provide information about intra-areal incident patterns that could enhance planning and reporting activities.
