Abstract
Land cover data are an essential input into a wide array of models including land surface process models and weather/climate models. The Dynamic Land Cover Dataset is the first nationally consistent and thematically comprehensive land cover reference for Australia. It provides a basis for reporting on change and trends in vegetation cover and extent. The Dynamic Land Cover Dataset Version 2 is a suite of of ISO (ISO 19144-2) compliant land cover maps across the Australian landmass. The series of maps presents land cover information for every 250m by 250m area of the country for rolling two year intervals from 2001. Each map has been generated by applying a sophisticated time series analysis technique known as Dynamic Markov Chain modeling to two years of MODIS Enhanced Vegetation Index (EVI) data. The Dynamic Markov Chain modeling was used to classify each pixel based on the way that pixel has behaved over a two year period. The maps contain 33 land cover classes which reflect the structural character of vegetation, ranging from cultivated and managed land covers (crops and pastures) to natural land covers such as closed forest and open grasslands. The series of maps have been compared with over 30,000 independent ground data points provided by State, Territory and Federal Government agencies. The sequence of maps shows how Australian land cover is changing over time.
