This map depicts, in dark green, parts of the landscape that are intrinsically prone to lightning ignition. Actual ignitions also require a storm to generate lightning that strikes fuel that is dry enough to support a fire. Note that often this is large, elevated fuel, not the fine fuel covered by normal Fuel Moisture Content estimates.
The work is an implementation of: McRae, R. (1992). Prediction of Areas Prone to Lightning Igniton, International Journal of Wildland Fire 2(3): 123-130. As foreshadowed in that paper, it is further enhanced by the function:
((MSER-30)^2+1)^-0.5*Macro-Scale Slope/22
The digital elevation model used is from NASA's Shuttle Radar Terrain Mapping mission.
This map is based on a standard 1:100,000 scale map tile (ref: GeoScience Australia), outlines in grey. Grid north (Zone 55) 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 MGA94 Zone 55 in the west and zone 56 in the east.
