Today, 3D geo visualization of flood data is perceived as a more realistic and detailed solution for making decisions regarding flood mitigation and adaptation measures. In this paper, after a multi-criteria comparative study of four virtual globes used in the visualization of geospatial flood data, it is found that CesiumJS stands out the most from the other solutions, with a score close to 100% on all criteria grouped in four categories (visualization, interaction, quality of support and experiences). Using CesiumJS and other libraries, we proposed a 3D web solution to dynamically simulate and visualize floods in urban areas of Cameroon. The main objective of this tool is to strongly involve water experts, policymakers and the general public in flood management. With-out considering a precise 3D city model, this tool, however, represents a good compromise be-tween the quality of flood management and the cost of better Flood Management by an expert.

Abstract
Today, 3D geo visualization of flood data is perceived as a more realistic and detailed solution for making decisions regarding flood mitigation and adaptation measures. In this paper, after a multi-criteria comparative study of four virtual globes used in the visualization of geospatial flood data, it is found that CesiumJS stands out the most from the other solutions, with a score close to 100% on all criteria grouped in four categories (visualization, interaction, quality of support and experiences). Using CesiumJS and other libraries, we proposed a 3D web solution to dynamically simulate and visualize floods in urban areas of Cameroon. The main objective of this tool is to strongly involve water experts, policymakers and the general public in flood management. With-out considering a precise 3D city model, this tool, however, represents a good compromise be-tween the quality of flood management and the cost of better Flood Management by an expert.

Abstract: (french)
Aujourd’hui, la géovisualisation 3D des données d’inondations est perçue comme une solution plus réaliste et détaillée pour prendre des décisions concernant les mesures d’adaptation et d’atténuation des effets d’inondation. Dans ce papier, après avoir fait une étude comparative multicritère de quatre globe virtuel utilisés dans la visualisation des données géospatiales des inondations, il en ressort que CesiumJS se distingue le plus des autres solutions, avec un score proche de 100 % sur l’ensemble des critères regroupés en quatre catégories (Visualisation, Interaction, Qualité du support et Expériences). En utilisant CesiumJS et d’autres librairies, nous avons proposé une solution web 3D pour simuler et visualiser dynamiquement les inondations dans les zones urbaines du Cameroun. L’objectif principal de cet outil est d’impliquer fortement les experts de l’eau, les décideurs et le grand public dans la gestion des inondations. Ne prenant pas en compte un modèle de ville 3D précis, cet outil représente toutefois un bon compromis entre la qualité de gestion d’inondation et le coût d’une meilleure gestion d’inondation par un expert.
