Efficient AIS Data Processing for Environmentally Safe Shipping

Even though ship accidents at sea has many economic and environmental implications on Greece, ships formulate routes according to their best judgment. In this study we take a dataset spanning in 2.5 years from the AIS network, which is transmitting in public a ship's identity and location, and we load it in a trajectory database supported by the Hermes MOD system to begin an analysis by extracting safety related statistics for the dataset. Simple queries as well as more complex ones (e.g. OD-Matrix) on the dataset illustrates the capabilities of Hermes and allows to gain insight on how the ships move in the Greek Seas. One of the newest challenges that emerged during this process is that the amount of the positioning data is becoming more and more massive. As a conclusion, a preliminary review of possible solutions to this challenge along with others is mentioned.
