We want to apply map symbols in the web map service(WMS), and allow a flexible customization of the WMS visualization. To achieve this, we studied the Styled Layer Descriptor implementation specification(SLD), which support WMS, work on the publishing method for map symbols for the web, and worked on the analysis of WMS and SLD. We designed the structure of the web map symbol service, and put forward the coupling method between web map symbol service and WMS based on SLD, in order to solve the problem of not being able to change map style by WMS on WebGIS. We validated our metkodby a prototype system. The experiments show that this method can effectively associated map symbol service with WMS, allowing a flexible and customizable WMS visualization.
