Data Visualisation / Astronomy Challenges to commonality How does Astronomical visualisation differ from others? Infrastructure Requirements Grid Requirements Nature of Astronomical Data & Visualisation Largely Static 2d tables (catalogues) pixel images Metadata (some) Exploration – largely visual Hypothesis testing – largely mining Challenges Lots of loud astronomers Hard to Normalise, esp between disciplines. Yet need to retain access to ‘raw’ data. Objects move… Large images / tables Æ sample, aggregate Finding out about existing tools More Challenges Special Science Requirements for tools (eg finding distances on images) Æ plugins Noisy data (but bio / meteo have same problem) Incomplete/high error models (bio / meteo again) Inherent Mk 1 eyeball limitations. Solid cubes. Make use of colours, shapes, movies. 7d on paper. Need pre-visualisation methods AND retain access to raw data. Grid Requirements Reliability – the right data to the right machine! Speed & Latency (for visualisation) Collaboration (not yet) Integration – access to eg stats services Easy / simple controls – focus on science not infrastructure. Summary Tools exist ‘generalising’ + ‘modularisation’ Expertise exists – ‘synergy’ with professional visualisors Astronomy data not unique – ‘synergy’ with other disciplines
