These outliers can correspond to illegal activities that could be related with illegal immigration, drugs trans-shipments among others. We developed process tools that based on any elec-tronic vessel position systems, like Automatic Identification System (AIS) data, it is possible to extract routes in an unsupervised approach. At the same time identify non-conformities based on AIS data signal lost and to identify situation when two or more vessels are approaching close to each other, called the rendezvous. Keyphrases: AIS, Outliers, Vessel, rendezvous, trajectory
