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.
Note that laboratory and numerical studies have caused the name change to Vorticity-Driven Lateral Spread.
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. Note your local variations for true and magnetic north before using those.
The limited annotation data are from GA's 1:1,000,000 scale products.
This map shows a 10km map grid, on the relevant MGA94 Zone. All elevation data uses SRTM v2 data.
