| Drought is commonly portrayed using images of cracked earth, dry dams and empty river beds. However, these 2-dimensional representations illustrate the impact of drought rather than drought itself and ignore the rich 4-dimensional spatio-temporal variablity which characterises drought as a natural hazard. Improved visualisations of drought are needed to increase public understanding and assist the research community in understanding its drivers. WebGL is explored as a medium for contructing interactive drought graphics that go beyond displaying drought impacts and address the multi-dimensionality of the problem. |
