Résumé partiel
The Moderate Resolution Imaging Spectroradiometer (MODIS), flown on board the Terra Earth Observing System (EOS) platform launched in December 1999, produces a land covered change product. This product is expected to be of better quality than LCC (Land Cover Change) products based on operational satellites (notably GOES and AVHRR), due both to improved spectral resolution and higher spatial resolution of the MODIS instrument .The plans for the MODIS instrument include the generation of improved global data sets. Vegetation Indices are simple, robust, empirical measures of vegetation activity at the land’s surface. They are widely utilized for global monitoring of both spatial and temporal variations in vegetation at high precision. The MODIS VI products will improve upon currently available indices and will be used to more accurately monitor and detect changes in the state and condition of the Earth’s vegetative cover. Vegetation indices will also play a role, as ’intermediaries’ in the derivation of vegetation biophysical parameters, such as leaf area index (LAI), percent green cover, and fractional absorption of photosynthetically active radiation (fAPAR).MODIS as one of sensors of TERRA, begin numerous to pay close attention to the thing as soon as lifting off. Its preferential policy and one’s own wave band characteristic used free, covered and studied ecological environmental monitoring , climatic change analysis and the earth’s surface which launch the whole world and area by the change, the past NOAA-AVHRR that use there are more advantages relatively. EOS/MODIS data turn of the century most attractive star year datum source one of in the world, its extensive regional coverage rate and resolution ratio of good time make it have wide prospect in using. Therefore a lot of MODIS ground that country set up in succession accept and stand. The study on MODIS of our country utilizes beginning in recent years, it is less to utilize on its, mostly still at the starting stage.
