520 | 3 |a"The aim of this work is to increase the capabilities of position report databases, like Defence Research and Development Canada (DRDC)'s Maritime Situational Awareness Research Infrastructure (MSARI) or the Global Position Warehouse (GPW). For this purpose, a position report is a record of identity, location and time that is reported by a particular vehicle, usually a ship, in order to indicate its own position at a particular moment. The Automatic Identification System (AIS) provides most of the position reports in the databases cited above, but Vessel Monitoring Systems (VMS) and Long Range Identification and Tracking (LRIT) are also prominent sources. Position report databases already allow for a wide range of queries based on characteristics of the reports themselves. DRDC Atlantic is interested in providing the ability to construct and manage interpolation queries that rely on inference about what happened between position reports. The goal of this contract was to construct fundamental infrastructure, data structures and algorithms that are required for such query-building. The long term goal of this work is to make it easy for operators with little database training to construct interpolation queries. In support of these goals, an Interpolation System was developed to convert AIS position reports into tracks, which are then stored in an Interpolation Database. These tracks are so constructed as to avoid crossing land obstacles that are defined using polygons. This obstacle avoidance capability is the major novelty of the work"--Abstract, page i. |
