• Usually, remote sensing data and sequences are under-used, though their content in information is very high (shapes evolution, correlations, . . . )
• HR Images would also help to identify the landscape elements (grass strips, hedges,. . . )
• In classical approaches: uncorrelated noise, diagonal error covariance matrices
• How to provide observation error covariance matrices adapted to spatially correlated errors? [2]
• Focusing on the observations operator description, and distances definition in the DA scheme
