The Piraeus AIS Dataset for Large-scale Maritime Data Analytics

The Piraeus AIS Dataset for Large-scale Maritime Data Analytics

Highlights
AIS data collected by the University of Piraeus' AIS receiver Contributors: Andreas Tritsarolis; Yannis Kontoulis; Yannis Theodoridis Data Science Laboratory, University of Piraeus Abstract The advent of Big Data and streaming technologies has resulted in a swarm of voluminous, heterogeneous information, especially in the domains of Internet of Things (IoT) and transportation. Focusing on the maritime field, we present a dataset that contains vessel position information transmitted by vessels of different types and collected via the Automatic Identification System (AIS). The AIS dataset comes along with spatially and temporally correlated data about the vessels and the area of interest, including weather information. It covers a time span of over 2.5 years, from May 9th, 2017 to December 26th, 2019 and provides anonymised vessel positions within the wider area of the port of Piraeus…

ST-Visions

ST-Visions

Highlights
A Python-based library for interactive spatio-temporal data visualization. Overview ST_Visions (Spatio-Temporal Visualizations) is a python library, able to interactively visualize spatio-temporal data in a quick-and-easy way. Based upon the functionality of Bokeh, and further extending it, we are able to create powerful and cohesive visualizations (and/or online dashboards), for large or streaming spatio-temporal datasets.

i4Sea: Surveillance and Analysis of Marine Areas Movement using Big Data

i4Sea: Surveillance and Analysis of Marine Areas Movement using Big Data

News
The final review of the i4Sea project was successfully held on November 11, 2021. During this 3-year project (July 2018 - July 2021), an innovative platform for the collection and analysis of large marine surveillance data was developed. The vision of the project was to efficiently and quickly process, integrate and analyze these data in order to create (a) a “Combined Real-time Business Image” and (b) a “Combined Historic Image” of Marine Surveillance. More details about i4Sea are available in the project’s official web site.
