Summary: Classical methods for satellite image analysis appear inadequate for the current bulky data flow. Thus, making the interpretation of such images automatic becomes crucial for the analysis and management of phenomena changing in time and space, observable by satellite. Consequently, this work aims to contribute to the dynamic land cover cartography from satellite images, by expressive and easily interpretable mechanisms, and by explicitly taking into account structural aspects of geographic information. It is part of the object-based image analysis framework, and assumes that it is possible to extract useful contextual knowledge from existing maps. Thus, a supervised parameterization method of an image segmentation algorithm is proposed, taking a segmentation derived from a land cover map as reference. Secondly, a supervised classification of geographical objects is presented. It combines machine learning by Inductive Logic Programming and the Multi-class Rule Set Intersection approach. Finally, prediction confidence indexes are defined to assist interpretation. These approaches are applied to the French Guiana coastline cartography. The results demonstrate the feasibility of the segmentation parameterization, but also its variability as a function of the reference map classes and of the input data. Nevertheless, methodological developments allow to consider an operational implementation of such an approach. The results concerning the object supervised classification show that it is possible to induce expressive classification rules that convey consistent and structural information in a given application context and lead to reliable predictions, with overall accuracy and Kappa values equal to, respectively, 84.6\% and 0.7. In conclusion, this work contributes to the automation of the dynamic cartography from remotely sensed images and proposes original and promising perspectives.
