Abstract

The aim of this project is to design a streaming framework for the visualization of three dimensional large-scale geospatial data. A simple idea is implemented: just the bare necessities have to be loaded and rendered. The 3D scene is so incrementally built and dynamically updated run-time, taking into account the movements of the camera and its field of view. To effectively and efficiently achieve this behavior, proper mechanisms of tiling and caching have been implemented. The framework implementation focuses on textured terrain streaming. Despite the scope limitation, the defined streaming paradigm has general validity and can be applied to more complex 3D environments. The addition of other features on top of the terrain is straightforward and does not imply substantial modifications to the framework. In order to make the framework standard compliant and platform independent, it has been designed to work with OGC web services and the widely adopted web-based approach has been chosen. As a result, any WebGL compliant browser can run web applications built on top of this framework without the use of plug-ins or additional software
