Research on Mobile SVG Map Service Based on Java Mobile Phone

One of the key issues to realizing map services in the GIS mobile system is to overcome the physical limitation of the mobile computing device, such as storage, CPU etc. This paper first proposed the resolution for mobile SVG map service on mobile phone, and then focused on the research of loading and displaying of mobile SVG map. The experiment shows that the mobile SVG map can be zoomed perfectly. The loading and displaying time of the mobile SVG map is non-proportional to the size of the map, and approximates to the parallel shift on the time axes.
