Terrain Generation

With the uprising deployment of large-scale environmental simulations, as well as the wide applications of the GIS data in the simulation models, the traditional modeling methods have been difficult to meet the requirements of terrain generation of large areas. In this paper, we study a new terrain database modeling process based on Celerity/TerraVista, which uses the techniques of image compression, block optimization, and level of detail (LOD) , for terrain generation of large areas. Tis new modeling process has been applied in our independently developed simulation system and has achieved good results.

With the development of network and information technology, it is highly desirable to create 3D geoscience applications in the network environment. However, construction of web-based 3D terrain model is one of the foundation works of 3D geoscience applications in the network environment. This paper presents a new method of constructing large-scale 3D terrain model based on Extensible 3D (X3D). In this way, we first use Geospatial components of X3D to build 3D terrain model by using DEM as the data source, then we publish the 3D terrain model to the internet with a architecture of Brower/Server and plug-in technology. To promote the display performance of large-scale 3D terrain model, We presents an approach that using the Level of Detail (LOD) technology to simplify the 3D terrain model. The application results show that the method this paper presented has advantage of easy to integrate with other network system, thereby easy to realize data sharing and interoperation; the method also has virtues of fast display speed, high ability of interaction. It’s an effective method for constructing large-scale 3D terrain model in network environment.

In this paper we present a key data structure and associated render-time algorithm for the combined display of multi-resolution 3D terrain and traditional GIS vector data, by combining a fast GPU-based terrain solver, which is designed to create fully 3D scenes that deliver the best possible quality and do not require dynamic texture generation and handling. Level of detail terrain models and vector maps are created, and the server-client architecture is presented. The application provides an effective way for powerful access and manipulation of large-scale real datasets, which represents a basic mechanism for 3D GIS interface and exploration tools.
