Abstract :
Buffer analysis is one of the most important GIS functions to take spatial analysis. Based on our experience on EO data parallel processing, we take buffer generation as an example to research how to accelerate the speed and scale of GIS operations. This paper analyzes the procedure of the original sequential algorithm, and then gives out the mechanism of the parallelization. As a result, it will be easily assembled into OGC WPS container on a grid environment as both standard Web-service and enhanced WPS service. Some interested examinations also will be involved in this work to prove such technical approach.
