This report describes progress to date on a sub-element of the Naval Mine Countermeasures (NMCM) project, under the Battlespace Characterization work element. The goal of the work is to provide a tool which will assist the Royal Canadian Navy (RCN) planners in assigning Route Survey effort and resources. Change detection is most commonly used in post-mission analysis of seabed survey imagery, which compares new survey imagery against a historical database of imagery in significant areas of harbours. Changes to the seabed that occur naturally or by human activity can cause false alarms if the historical database is stale. The research program addressing this question has proceeded along two lines: 1) compilation of a seabed survey dataset from test sites in Halifax Harbour and 2) development of a model for prediction of areas where the seabed is most changeable. Areas with a high degree of changeability should be resurveyed more frequently to maintain a viable database compared to areas where there is little change over time. Collection of the survey dataset is ongoing, with the assistance of the RCN. A model framework has been developed in ArcGIS with some elements included, based on prior work by the UK Hydrographic Office.
