Abstract
The Automatic Identification System (AIS) is a maritime system mostly used for automatically exchanging
tracking and other relevant information between vessels. It supports decision making of nautical personnel such
as master mariners. AIS data are multivariate including many aspects for identification and localization of ships
and for navigation. However, during navigation not all AIS data are made visually available to the nautical
personnel. In this paper, we propose a glyph-based visualization consistent with currently used encodings for
intuitively and effectively encoding further so far missing AIS data attributes on radar screens. Proposed
extensions aim at increasing maritime safety by helping mariners to assess traffic situations. We applied our
visualization methods to real-world data recorded at the German North Sea coast and evaluated them with the
help of an expert group.
