Conclusion11 th International Symposium for GIS and Computer Cartography for Coastal Zones ManagementThis paper introduced a network model taking into account ice conditions to simulate feasible shipping paths betweenzones of interest in the Arctic. This analysis is based on the Ice Numeral model to assess if a ship can navigatein specified icy areas. A shortest path analysis based on Dijkstra’s algorithm has been proposed. Bathymetry couldalso be taken into account in order to restrict the graph network depending on ship’s draught. As this feasible pathsimulation relies on sea ice charts, it could be used to simulate future maritime traffic using ice prediction models(Maurette, 2010). Moreover, the maximum and minimum ice numerals aggregated for each month can be used asbounds for a statistical analysis on the likelihood of traffic occurring in specified areas.AcknowledgmentsWe acknowledge the Department of National Defence for supporting this research, and the Canadian Coast Guardfor providing the historical ship traffic data.ReferencesCanadian Ice Service (2009), Canadian Ice Service Arctic regional sea ice charts in SIGRID-3 format.
