Analysis and validation of a methodology to evaluate land cover in the Mediterranean basin using multitemporal MODIS data

In this work two techniques for the classification of multitemporal MODIS data were compared. Especially, it was applied a procedure to identify the different land covers in Sardinia, based on decision tree classification, analyzing the seasonal variations of coverage and assessing their accuracy. The accuracy of results was assessed through the use of a statistical approach based on confusion matrix, comparing the accuracy of estimates from the two classification techniques for MODIS images of the year 2000. In the present study are discussed the first results on the analysis; they show the feasibility of using the MODIS 250 in data for the monitoring of land cover in areas with a mixed vegetation such as Sardinia.
