In this paper, the Donghekou landslide-debris flow triggered by the 2008 Wenchuan earthquake was selected as a case study. Terrain information can be extracted efficiently and freely from GE using an application programming interface (API) and then used to generate DEM. The emergence of the virtual earth platform of Google Earth (GE) provides new possibilities for generating terrain models.
#Vitual earth 3d professional
For example, historical topographic maps exist mostly in paper format, which is not conducive to spatial analysis, while interpretation of remote-sensing images generally requires professional knowledge at a high cost.
The method proposed in this study may solve some limitations existing in other more traditional methods. Based on the terrain model, numerical simulations can be conducted and the results integrated with virtual earth to perform 3D visualization and visual analysis. The main aim of this study is to propose a low-cost and efficient method based on virtual earth to generate a three-dimensional (3D) DEM. Generating digital elevation model (DEM) for such geological disasters allows the rapid identification of affected areas, which is essential for emergency response and hazard mitigation. Info-points (description buttons that can be placed in the panorama), embedded pictures, video and audio can be added to the ready virtual tour.Sudden large-scale geological disasters can be triggered in mountainous areas by events such as earthquakes, rainfall, volcanic eruptions, or human activity, leading to serious loss of life and property. We develop virtual tours which are suitable for all browsers, support both Flash and HTML5 technologies and are compatible with different mobile devices and virtual reality glasses (including Samsung Gear VR). Our team creates high-quality 360° photo-panoramas with resolution from 1 to 3 gigapixel and carries out professional post-processing and corrections of any complexity. Info-points (description buttons that can be placed in the panorama), embedded pictures, video and audio can be added to the virtual tour. Ready 360° photo-panoramas cover up all the space around the camera 360x180 degrees without black spots at both nadir and zenith viewing angle. Panoramic video covers up all the space around the camera 360x180 degrees without black spots at both nadir and zenith viewing angle. For aerial shooting we usually use drones with the fully gyro-stabilized unique suspension. We use different types of moving and fixed objects (tripods, monopods, cars, helicopters, building cranes, etc.) to record videos. We develop virtual tours which are suitable for all browsers, support both Flash and HTML5 technologies and are compatible with different mobile devices and virtual reality headsets (including Samsung Gear VR). Our team creates high-quality 360° photo-panoramas with 35000x17500 pixels resolution (in the equidistant projection) and carries out professional post-processing and corrections of any complexity.
