Software Engineering – Visualisation of a complex model. Using CSIRO’s TAPPAS as an example, present the key challenges and success factors in engineering data visualisations.

TAPPAS (Tool for Assessing Pest and Pathogen Airborne Spread) is an online tool for modelling the dispersal of living organisms, developed through a CSIRO, Bureau of Meteorology and Intersect partnership.  TAPPAS uses  global air circulation data from the BOM’s numerical weather prediction model and models this using the HYSPLIT dispersion system  for computing simple air parcel trajectories.  TAPPAS combines this with knowledge of the organism’s biology, and delivers these in an easy to use interface that presents results as risk maps.

In five minutes we will cover some of the key challenges and successes of this project from an engineering perspective, and show a couple of the dispersion visualisations.

With the growth in demand and importance of data visualisation, the aim of this presentation is to help other delegates  understand some of the key success factors in engineering visual data from complex models.


Craig has over 20 years experience in software engineering, architecture and product management in higher education as well as local and global private companies.  From architecting and building the number one australian online shopping site in the early 2000’s to developing global identity management programs for over 20 million users Craig has designed and built systems that solve unique and complex problems with adoption, scalability and security.  As engineering manager of Intersect Australia for the last year Craig has overseen the delivery and development of a number of research software engineering products such as TAPPAS and CloudStor Collections.
