A Grid-based Marine Traffic Hotspot Detection Algorithm on SpatialHadoop
Abstract— Owe to the establishment of modern navigation and communication networks, maritime vessel trajectory data becomes increasingly available. These data sets are always huge and usually heavily skewed, finding hot spots area among maritime traffic data is critical for real time applications ranging from military surveillance to transportation management.In this paper, we proposed a grid-based hotspot detection algorithm on maritime traffic data. By gridding the spatial area into small buckets, it take the vessels density on each bucket into further calculation instead of the location of each single moving vessel. In order to handle the big data set, the computation apply the SpatialHadoop framework which can establish the R-tree spatial index to enhance location data handling performance on MapReduce programming. Experiments on real AIS data shows that the method propose is effective and fast.
