This API provides access to ecomorphological assessment data for watercourses in the canton of Geneva, Switzerland, published by the Système d'information du territoire genevois (SITG). The underlying methodology was jointly developed by the Federal Office for the Environment, Forests and Landscape (OFEFP) and the Swiss Federal Institute for Water Resources and Aquatic Ecosystems (EAWAG) to evaluate the ecological and morphological condition of rivers and streams. The data supports environmental monitoring and water management analysis at the cantonal level, reflecting the national methodology applied to local watercourse networks.L'Office fédéral de l'environnement, des forêts et du paysage (OFEFP) et l'Institut fédéral pour l'aménagement, l'épuration et la protection des eaux (EAWAG) ont élaboré une méthode d'analyse pour l'appréciation écomorphologique des cours d'eau en Suisse. Cette méthodologie a été publiée dans les c…
