ABSTRACT: Great attentions have been paying by many shipping countries to the digital chart application in the field of maritime traffic. To resolve ?Information Isolation?, numerous Web chart systems have been developed over the world. Most of them, however, are vector chart based. This paper advances a method to build web chart system with raster data. System architecture, coordinate transformation as well as the splitting and rendering of raster charts are introduced in this paper. By using the pre-rendered chart tiles, the web raster chart system can be accessed with higher speed than most vector chart based web rendering system in wide bandwidth network. The experiment also shows the rendering error of this method is small enough for many kinds of application.
