Big Data Institute S-AIS Data Mining Casey Hilliard

(Related) Institute Goals To build capability within the institute as an international centre for AIS data modelling and analysis techniques To partner with researchers and institutions to who may avail of the HQP and hardware available to the institute

MEOPAR/exactEarth/Dalhousie S-AIS Initiative Supported by the Institute (data hosting) Database, backup, analytical support Geospatial DB platform (Postgis) Also Solr, IBM PureData assets available Fast spatial query / prototyping webapp developed on Solr index IBM PureData also prototyped as fast “static” data access

Earlier Works: Vessel Traffic Analysis Trajectory clustering Knowledge-based clustering of ship trajectories using density-based approach (Liu et al. 2014) Anomaly detection Anomaly detection in maritime data based on geometrical analysis of trajectories (Soleimani et al. 2015) Ship movement anomaly detection using specialized distance measures (Liu et al. 2015)

Global Fishing Detection Using S-AIS Data Fishing activity detection algorithms developed in collaboration with Dal Biology (WormLab) “Improving fishing pattern detection from satellite ais using data mining and machine learning” (de Souza, Boerder, et al. 2016) Initially detecting trawler and longline; purse seiner in development Improving, visualizing “Identifying fishing activities from AIS data with Conditional Random Fields” (Hu et al. 2016) Refining performance by including distance from shore Recently Incorporated into webapp Leveraging Solr index Development ongoing

Webapp Interface

Webapp “Demo” AIS Reports with detected fishing Weekly for 2013-07 Each image = aggregate over 1 week Interactive map Scalebar approximate*

Upcoming Works: Vessel Remoteness Visualization Webapp - Animation of vessel remoteness - Measured against vessels and communities - To increase awareness of risks in remote areas of vessel operation Ballast Water Compliance Analysis - Comparative analysis of vessel ballast reports against transits - To assess feasibility / available methods for automation (tech demo) - Including novel enrichment (-- bathymetry)
