By computing the difference between the bands of the image of the day and “the rolling mean” of these bands, one define a change index. This index together with other criteria are analysed in a decision tree to detect fires or burnt areas.
This automatic classification has been successfully applied for the detection of fires in Spain, Guinea and Sudan.
Scope of these preliminariy studies is to set up a multi-sensor alarm system for civil protection, farmers, NGOs, citizen… After a qualification phase, e-mail or SMS will be sent to the people for events occuring within their area of interest.
