3-dimensional visualization is an integral part of satellite data processing and adds great value in terms of interpretation and effective presentation. 3D visualization requires large amount of data and compute power to map the data into underlying terrain model. Grid Technologies enable us to effectively harness the vast computational resources available at geographically separated data reception centers/stations. In this paper, we propose a service-based closed community grid for generating 3-dimensional visualization of large topographic area in near real time. The key aspect is that the end user is oblivious of the processes involved such as searching and transferring of data, processing the data and aggregating the partial results for the underlying activities.
