Zonazione con l'uso di immagini da satellite di aree percorse da incendi nella Sardegna settentrionale

The work that is being carried out in the Photogeology Laboratory of the Sciences of the Earth Department in Cagliari, aims at the setting-up of a methodology of study for the monitoring and the enviromental evaluation of the areas struck by fire, in the field of Remote Sensing of images by satellite. The first elaborations of the research programme are presented in this work. A northern Sardinia zone, particularly interested by fire in the latest years, has been chosen as a sample area. TM Landsat images, with a spatial resolution of 30 m, have been elaborated in order to plot clearly and with highest definition the area taken into consideration. Particularly, two series of TM bands have been used relative to two passages of the satellite, the first of 18.6.88 and the second of 25.9.89. As a risult of the comparision between the two series of images concerning the same area, it has been possible to zone some areas struck by fire during the summer 1989.
