Operational Awareness for Advanced Firefighters & Fire Behaviour Analysts


Terrain data for operational purposes can estimated from published topographic maps. While the aspect of the side of a ridge will be rather constant, its slope value will depend on the scale at which you measure it – the finer you examine it, the greater the possible range of value will be. This scale should resolve details of about 5% of the headfire width. For most fires 1:25,000 topographic maps will suffice.
