Digital resampling for image processing and fusion of SSM/I data

Environmental parameters can be extracted from the integration of remote sensed images data coming from other sensors but they need a geolocation to allow the integration of these data. The geolocation process depends on several factors: Earth-satellite geometry, scanning geometry, mapping projection. Data fusion of preprocessed data can be done in the following ways:-addition of data of the various sources (overlay) without the same coverage;-real fusion of data (combination). Data fusion need data alignment and implies a common time base and a common spatial coordinate system. This article follows all environment parameter extraction as combination of the data coming from different SSM/I channels and a comparison with the same parameter computed with the IR data coming from Meteosat
