Landform component mapping of north west Victoria

dataset: NW_LANDFORM
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).

Resource Constraints

Use limitation
. Users should be aware that landform component delineation is fuzzy in that in most cases clear boundaries between landforms do not exist. In most instances only the mid and upper slopes and crests of sandy rises such as dunes and hummocks have been mapped. Users should refer to the final project report and "A study of the land of north-western Victoria" Rowan and Downes (1963) report. The report provides the methodology used to derive the landform dataset and identifies associated limitations, the Rowan and Downes (1963) report details the morphology and variation in landforms across the land systems of the Mallee.

Statement
Dataset Source: In 1963 Rowan and Downes published "Landsystems of north west Victoria" which broadly mapped and described land, land use, climate and vegetation patterns in the Mallee region of Victoria. From 2009 to 2011 landform components described within each land system were disaggregated using a 10 meter resolution digital elevation model. 19 landforms classes were mapped in total across dryland agricultural areas. These mapped landforms provided the basis for wind erosion susceptibility mapping (refer to separate metadata record). Dataset Originality: Derived
