My current project is the development of the Australian Cancer Atlas. The end result will be a publicly accessible , online, interactive map (think Google Earth) showing estimated standardised incidence ratio and excess hazard rates for many different types of cancers. I work with Cancer Council Queensland and the QUT Visualisation and eResearch (ViseR) team to combine our expertise in statistical spatial modelling, data visualisation, and UX and UI design. A mock-up example of the cancer atlas UI is shown below.
Note: the values indicated by this map do not represent real data and are provided for illustration only.
There are also plans to develop a new spatial model designed to avoid the issues of over- and under-smoothing, compare this model against other published methods using simulated data, and apply the model to real incidence and survival data which may be used in future versions of the cancer atlas. Other contributions include finding the best (or at least good) ways to represent uncertainty around estimates.
