SahulTime: Rethinking Archaeological Representation in the Digital Age

SahulTime is an experimental development project to explore how archaeological knowledge might best be represented within a digitally native mode. The system incorporates an interactive, zoomable timeline with a changing geographic view, time-aware icons and detail-boxes that can themselves express temporal visualisations. The core knowledge domain currently represented is Australian archaeology in the context of changing sea-level, but the visualisation concepts developed are more generally applicable at a global level on all timescales, and may offer a first step towards the ‘Digital Earth’ vision of a top-down interface for exploring the world and its history.
