Interactive Virtual Globe Service System based on OsgEarth

摘要

These online tools, led by the Google Earth virtual globe, are changing the way we interact with spatial data. This paper focused on how to develop a virtual globe-based interactive service system for risk assessment of dam-break in Barrier Lake. Unlike existing work, virtual globe technology was used as a medium for geographic visualization and analysis. Moreover, GIS spatial analysis and real-time interactive operation with the service system will also be implemented to support the simulation analysis of dab-break flood routing. The experimental results show that the scheme developed in this paper is efficient and feasible.
