A method based on airborne LiDAR data has been developed in order to obtain fuel model maps at a large scale and with high spatial resolution.

Using the tri-dimensional information derived from LiDAR, fuel structure and continuity is analysed, and then combined with information regarding the composition of the stand in order to define classification algorithms depending on the type of vegetation present.

The maps were obtained according to two different fuel classification systems: models specific to the Canary Islands and standard models from ICONA (the former Spanish Nature Conservation Institute) which are based on the American NFFL system.

The methods used can be easily extrapolated to other forests in other regions, and enable the maps to be quickly updated when future LiDAR flights become available. They provide reliable and useful information for the prevention and control of forest fires covering large areas
