Visualisation - the representation of data graphically, as a means of gaining understanding and insight. In more simple terms – it means looking at graphics in a different way so you can understand data/concepts more easily. ** Examples ** Animation – this/other presentations and computer screens 3D Applications – Google Earth/Google Maps Simulators and models – Secondlife ** Advantages ** We are able to see things around the world. We can get to places more easily with these systems- no more 2D maps Cost is nothing to look at things across the world using free applications like Google Earth We may be able to learn and understand things more easily – Computer animation ** Disadvantages ** Takes a long time to implement and change such systems if needed Some areas of maps may not be covered by applications Can’t always rely on technology It **does** cost for computer graphics and sometimes for applications ** Social and Ethical Issues ** Reliability Privacy – Google Earth/Google Maps Security Globalisation People and Machines
