This paper explores the application of the rose-diagram technique to the spatial characterisation of vegetation fires at both a regional and continental level in Africa. Earth observation from space by remote sensing satellites provides systematic and consistent measurements of a series of parameters related to vegetation fires and their environmental impact. The rose-diagram technique is a numeric approach. For each image, a reference point is assumed to be the origin of a polar plane and each fire pixel is connected to the origin generating a series of linear elements. The rose-diagram of fire frequency gives an immediate impression of biomass burning phenomena at regional scale.
