The evolution of geographic information systems is rapidly narrowing the gap between Geography and Computer Sciences. One of the examples is the increasing interest in geovisual analytics, a geographic form of visual analytics aiming at supporting knowledge discovery through the visual exploration of geographic data. This talk will present some of the key outcomes of an NSERC project looking at the visualization of fishing vessels movements. Large fishing vessels operating in Canada are tracked by the government in near-real time using vessel monitoring systems (VMS), proving a tool for fisheries enforcement activities. While VMS movement data have the potential to greatly help enforcement officers in their tasks, their actual use can be very challenging and time consuming due to the large volume of data being displayed, frequently leading officers to only detect the most obvious infractions or to focus on few vessels known for past illegal practices. This talk will present a set of approaches allowing to visually filter out movement data of lower interest to the experts, in addition to allow grouping movements of vessels sharing similar characteristics into common patterns. The usability of the system was tested with a number of fisheries enforcement officers working for the Canadian government.
