SVG is a promising standard for publishing geospatial data over the Internet. But when using SVG to publish very large geospatial dataset, we always have to wait a long time for the SVG map to load. The delay of loading SVG maps over Internet includes the network transmission delay, and the rendering delay in client side. This paper proposes a visual lossless data reduction method to reduce the data amount of SVG maps while preserving the visual effects (visual anti-distortion). In order to prove the proposed method is feasible and operable to improve the transmission and rendering performance of SVG maps over the Internet, we implement the method and use some sample data for method evaluation.
