“…Cannata and Marzocchi (2012) implemented a GRASS GIS with a GIS-embedded approach that solved the conservative form of the 2D shallow water equations using a finite volume method. Zhu et al (2015) proposed a risk assessment system of dam-break flooding based on virtual geographic environment platforms that could improve the efficiency of risk assessment and decisionmaking. However, the above-mentioned researches were primarily intended to integrate desktop applications, and little attention was paid to public participation (Sun et al 2015).…”

“…The characteristics of VGEs, especially for Environ Earth Sci geographic visualization and model integration, have attracted much interest from geoscientists, and an increasing number of applications are using VGEs for data processing, modeling, output visualization and simulation workflow management (Goodchild 2009;Xu et al 2011;Chen et al 2013;Lin et al 2013a, b;Li et al 2015;Wen et al 2013;Zhu et al 2015). Although remarkable progress has been made, much work remains to improve VGEs for simulation analyses of dam-break floods.…”

Geographic modeling and simulation is now regarded as a fundamental approach to geographic process mining and complex geographic problems, such as dam-break floods. With the rapid development of web services and network technologies in the context of GIS, it is possible to offer a new generation of geographic analysis tools that are based on new types of Web and computer-based geographic environments that are built for understanding geographic processes and problem solving. This paper focuses on the visual analysis and simulation of dam-break flood spatiotemporal process in a network environment. The simulations were implemented with HTML5, WebGL, Ajax and Web Service and other technologies and also included the rapid computation of spatiotemporal process models, B/S network architecture construction, three-dimensional scene rendering optimization and dynamic interaction analysis. Finally, a prototype system was constructed, and an experiment was conducted to analyze dam-break flood spatiotemporal process visually in a case study region in a network simulation. The experimental results show that the scheme addressed in this paper can be used to publish spatiotemporal process information, online impact analyses and three-dimensional visualization representations in a network environment that is suitable for browsing, querying and analysis. This scheme can be used efficiently to understand dam-break flood process and support dam-break risk management.

“…Xu et al developed a platform that integrated a computational grid and a VGE system with a meteorological model to improve model computational efficiency [15]. To enable researchers in various fields to collaboratively produce computer-aided geographic environments, researchers have developed collaborative model environments for conducting virtual flood experiments and air pollution simulations [16][17][18]. Concerning human geography, Song et al combined pathogen diffusion and crowd simulation models in a VGE to simulate crowd evacuations for urban management [19].…”

Abstract:The model environment is a key component that enables a virtual geographic environment (VGE) to meet the scientific requirements for simulating dynamic phenomena and performing analyses. Considering the comprehensiveness of geographic processes and the requirements for the replication of model-based research, this paper proposes a model base framework for a model environment of a VGE that supports both model construction and modelling management, resulting in improved reproducibility. In this framework, model management includes model metadata, creation, deposition, encapsulation, integration, and adaptation; while modelling management focuses on invoking the model, model computation, and runtime control of the model. Based on this framework, to consider the problem of ever-worsening air quality, we applied the Linux-Apache-MySQL-Perl stack plus Supervisor to implement the model base to support a VGE prototype using professional meteorological and air quality models. Using this VGE prototype, we simulated a typical air pollution case for January 2010. The prototype not only illustrates how a VGE application can be built on the proposed model base, but also facilitates air quality simulations and emergency management.

“…Although the thinking about VGEs never stops since it was born, and the continued development of VGEs has brought about significant achievements resulting from this concept (e.g., Goodchild 2009;Gong et al 2010;Konecny 2011;Lu 2011;Priestnall et al 2012;Lin et al 2013aLin et al , b, 2015 as well as related technologies and implementations (e.g., Xu et al 2011Xu et al , 2013Chen et al 2012Chen et al , 2013aZhang et al 2015a, b;Zhu et al 2015), there are still some misunderstandings about this 'new' branch of Geoscience. Questions generally are related to two concepts: the first concerns the differences between VGEs and game-like virtual worlds, similar virtual communities and cities, and digital earth; the second asks how VGEs can contribute to geographic research beyond traditional Geographic Information Systems (GIS) and Maps (Aydi et al 2013;Tung et al 2013).…”
