Due to climate change, natural hazards are happening more in recent days. Analyzing these changes and prediction of future hazards have been always a challenge in the field of Geographic information systems (GISs). Traditional GIS aims to use map versus globe for their models, standards, and analysis. With the advances on Discrete Global Grid Systems, a new research question has been raised on what if we adapt our traditional approaches into a Digital Earth rather than a map. Digital Earth (Global Grid System) has many advantages toward traditional maps. Some of them are multiple scale using hierarchical structure, no isolation of data on poles, explicit spatial resolution with zero variation, linearized grids, and one projection system for the whole globe. Besides, easy access, easy to search, copy, store, and share by all different types of users are other benefits for using Digital Earth. In this presentation, we would like to show a comparison on how we could overlay flood maps (Europe) in a traditional system like ArcMap and a new version of Digital Earth called Global Grid System (GGS). In addition, we will draw your attention to how visualization of these maps vary in both systems. We believe natural hazard risk management and decision-making definitely will benefit from a digital earth compared to a conventional GIS.
