A large percentage of these fires - 43% (DGF estimations) - are due to arson, which most of the times is related to land use change purposes. As an attempting to reduce the amount of intentional fires, the Portuguese legislation includes a set of laws that regulate the landuse change in areas devastated by forest fires. However, the control of these areas on the field is very expensive and time consuming, resulting in an ineffective procedure. In this study, we propose a more efficient and cost effective procedure to control the compliance of the legislation on burnt forest areas. This procedure is based on a system, BAMS (Burned Areas Monitoring System), built on a GIS that uses multi-temporal dataset of satellite images for detecting burned areas, and for characterizing land use before and after fire occurrence.
