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 4 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. Without considering a precise 3D city model, this tool, however, represents a good compromise between the quality of flood management and the cost of better Flood Management by an expert.
