Radiometric coregionalization of landsat TM and SPOT HRV images

Radiometric coregionalization of Landsat TM and SPOT HRV images is presented in the conceptual framework of the theory of regionalized variables using direct and cross-variograms, The main steps of this process are introduced, regularization, variographic analysis and selection of coregionalization model, and to show the practical aspects of this methodology two examples are analysed: the first considers the TM bands, and the second TM and HRV panchromatic bands. These models contain the basic information about the spatial intercorrelation for pairs of bands, and are necessary for multivariate geostatistical applications in remote sensing, such as integration, co-registering and co-estimation of multisensor data.
