Performance Evaluations of Vector-Raster Satellite Image Transfers through Web Services

Applications containing images include spatial and topological queries not requiring pixel-based information. In such applications, using vector representations of raster images is expected to give better performance results. In this paper, we setup a scenario to transfer a Landsat satellite image from one machine to another through web services. We perform the tests for both vector and raster forms of the same real-world Landsat-7 satellite images and analyze the results. We also take vectorization time into account for the vector data transmission and analyze if the transmission of images as vector data still has acceptable performance results.
