A conceptual framework for 3D visualization to support urban disaster management

Abstract

In this paper a conceptual framework is proposed, which aims at establishing link between 3D urban models’ characteristics and types of natural disasters. The framework is designed to serve for stakeholders and disaster managers for providing better selection of type of 3D model representations. The paper introduces parameters according to which the types of hazards can be classified. These parameters provide a background to decide on type of model needed. The LoD as defined in CityGML are investigated with respect to needed resolution for a specific data type. The presented framework is tested for visualization of vulnerability due to earthquake risk in Eskisehir, Turkey. The paper concludes with the discussion on advantages and disadvantages of the framework as well as outlining future research.GIS TechnologyOTB Research Institut
