Zones indicatives de dangersIndicative Hazard Zones
This API provides access to indicative hazard maps for the canton of Geneva, published by the Geneva territorial information system (SITG). These maps give a general, cantonal-scale overview of natural hazard situations, indicating broadly where and what type of natural hazards must be anticipated. In Geneva, the assessment covers only flood-related hazards. The dataset supports spatial planning and risk-awareness purposes by identifying areas potentially exposed to flooding across the canton, at a scale suited to general orientation rather than detailed site-specific hazard evaluation.Les cartes indicatives de dangers donnent une vue générale sur la situation de danger à l'échelle cantonale. Elles déterminent à une large échelle le lieu et le type de dangers naturels sur lesquels il faudra compter. A Genève, cette évaluation concerne uniquement les dangers liés aux inondations.…
