摘要
Land use/land cover monitoring and mapping is crucial to efficient management of the land and its resources.Since the late 1980s increased attention has been paid to the use of coarse resolution optical data.The Moderate Resolution Imaging Spectroradiometer(MODIS)has features,which make it particularly suitable to earth characterization purposes.MODIS has 10 products dedicated mainly to land cover characterization and provides three kinds of data:angular,spectral and temporal.MODIS data also includes information about the data quality through the‘Quality Assessment’product.In this paper,we review how MODIS data are used to map land cover including the preferred MODIS products,the preprocessing and classification approaches,the accuracy assessment,and the results obtained.
