摘要：In this paper we present a framework to generate a land cover classificatio n from coarse spatial resolution remotely sensed data acquired by NOAA-AVHRR sensor. We define a model for the pixels' content and a process allowing to compute the individual proportions of the different land cover types for each pixel. The method is based on a linear mixture model of re.ectances and exploits the good temporal frequency of NOAA acquisitions. The result provides a description in terms of land covers percentage within each NOAA pixel. A quality evaluation is performed on a test area for which high spatial resolution and temporal NOAA data are simultaneously available
