Data Dimension Reduction for Visual Analytics: A Case Study of Oil-in-water Detection

Many different sensors have been installed on board vessels, a new framework is urgently needed to form a Common Operational Picture (COP), to assist the on-board operations and onshore analysis. In this paper, based on the Visual Analytics framework, we present a spatiotemporal dimension reduction method based on a real world case of oil combat operation. With our prototype, we show that how dimension reduction of spatiotemporal data will improve visualisation and ease analysis.
