Inventaire cantonal des arbres isolésCantonal inventory of isolated trees
This API provides access to a layer centralizing all existing records of isolated trees located outside forests in the canton of Geneva, Switzerland. It results from the digitization of the 1976 historical inventory, subsequently updated regularly by local authorities. The dataset is a flattened view of the relational ICA (Inventaire cantonal des arbres isolés) database. It is maintained by the Système d'information du territoire genevois (Geneva territorial information system) and is accessible without authentication, providing free public access to tree location and attribute data for the canton.'Cette couche centralise tous les relevés existants d'arbres isolés situés hors forêts sur la canton de Genève. Elle est le résultat de la digitalisation de l'inventaire "historique" de 1976, mis à jour régulièrement par les collectivités. C'est une mise à plat de la base relationnelle ICA avec une…
