Abstract: Earth Observation satellites collecting both optical and SAR imagery deliver frequent, essential data for monitoring crops throughout the growing season. The integrated approach is being initially tested for sugarcane monitoring in the Cauca Valley (Colombia), but it is planned to extend it to other crop types and geographic area. Within the DINOSAR Project, we introduce an innovative approach that integrates data from both sensor types. The method uses Dynamical System’s Theory to optimally fuse radar, optical, and auxiliary data. It also enables the incorporation of in-situ measurements and crop growth models, resulting in more accurate and reliable crop monitoring. The integration methodology is designed to help farmers enhance productivity while lowering costs related to fertilization, pesticide use, and water consumption, ultimately reducing environmental impact.
