Etude sur la Comparaison des Donnees Images Produites Par des Satellites de Caracteristiques Diffeentes (Comparative Study of Image Data Produced by Satellites with Different Characteristics)

摘要

The methodology for combining imagery from different satellites involves choosing a reference and, by appropriate tansformations, associating several spectral responses of a target, and then reducing these responses to conditions which permit the juxtaposition in space (geometry and resolution), in time, and from the point of view of their radiometric calibration. Procedures are reviewed using examples from oceanography, geology, and the natural milieu to demonstrate feasibility and interest combining imagery from satellite imagery.
