A polygonal dataset of mapped landforms in the Victorian Mallee. The dataset was created from the disaggregation of land systems originally defined by Rowan and Downes (1963). The disaggregation primarily involved an analysis of a 10 metre grid Digital Elevation Model (DEM) provided by the Department of Sustainability and Environment. The analysis included the use of the UPNESS index from the Fuzzy Landscape Analysis GIS (FLAG) model, Multi-resolution Valley Bottom Flatness (MrVBF) index, DEM derivative surfaces (such as slope, curvature, aspect and relative elevation) in combination with expert opinion, field observations and other supplementary datasets (such as aerial imagery, radiometrics, vegetation and GMU). The dataset was created in a staged approach through 4 project phases. The project was sponsored by the Mallee Catchment Management Authority with funding from the Federal government's Caring for our Country initiative. The final project report, "Disaggregation of landform components within land systems of the Mallee", and the Rowan and Downes (1963) report , "A study of the land of north-western Victoria", should be referred to when analysing or utilising this dataset. The landform component mapping was supplemented and refined during a "Wind erosion susceptibility mapping" project conducted in 2011. Details of changes are included in the associated project report (refer to that metadata record).
