Semi-automatic extraction of ship lanes and movement corridors from AIS data

In this paper two methods for the semi-automatic extraction of major ship lanes and associated corridors of ship movement based on the processing of point information from AIS (Automatic Identification System) are compared: 1) based on the clustering of way points, and 2) trajectory segment clustering. In the first one, distinct points are first clustered and generated nodes are connected with straight paths. In segment clustering, course partitions with similar positioning and heading are grouped together. Additionally, shipping corridors are generated around each ship lane for each method.
