Cassia® is an innovative approach of ecosystem mapping based on artificial intelligence tools resulting from scientific research. The innovative Cassia® approach enables professional experts (ecologists, soil scientists, agronomists, planners, etc.) to transfer their expertise to large areas (up to several hundred km2) in a fast, reliable and repeatable manner. Cassia® thus provides managers with decision-support tools (DSTs) offering precise and reusable information that can be updated on demand.
