This is a meso-scale terrain model. There may be micro-scale VLS events not covered by this model. Always assess the landscape for lee-slope problems, especially if FMC is low. Note that laboratory and numerical studies have caused the name change to Vorticity-Driven Lateral Spread.
This map reflects work in:
Sharples, J.J., McRae, R.H.D. & Wilkes, S.R. (2012) Wind-terrain effects on the propagation of wildfires in rugged terrain: fire channelling. International Journal of Wildland Fire, doi:10.1071/WF10055. A draft of this is available here.
It is important to understand this before using this product operationally. Fundamentally if a spreading wildfire enters a local channelling event, it can spread in two directions at once and escalate violently, endangering fire crews.
This map is based on a standard 1:100,000 scale map tile (ref: GeoScience Australia), outlines in grey. Grid north is to the top of the page.
The limited annotation data are from GA's 1:250,000 scale products. Not for navigation.
This map shows a 10km map grid, on the relevant MGA94 Zone. All elevation data uses SRTM v2 data.
