ANALYSIS AND VALIDATION OF A METHODOLOGY TO EVALUATE LAND COVER CHANGE IN THE MEDITERRANEAN BASIN USING MULTITEMPORAL MODIS DATA
Journal Title: Present Environment and Sustainable Development - Year 2010, Vol 4, Issue 4
Abstract
Land cover composition and conversions are important factors that affect ecosystem condition and function. This study explored the use of 250 m multitemporal MODIS NDVI 16 day composite data to detect land cover change between 2005 and 2008 in Sardinia. We used a supervised classification procedure, based on the decision tree, to estimate land cover change and afterwards we assessed the accuracy. The methods and results detailed in this article apply only to non-agricultural areas. The main aim of this study is to propose a monitoring model to evaluate seasonal and interannual land cover change and utilize the information to evaluate the state of vegetation for the assessment of environmental risks. The first results show that the MODIS data are useful to evaluate the land cover change in areas with heterogeneous vegetation like Sardinia, allowing a continuous monitoring and planning of environmental management.
