<p>A system of processing map images includes a Web Mapping Service (WMS) for storing map images. A WMS proxy is operative with the WMS and receives from a client a request for a map image for display at the client. A WMS proxy includes a tile broker module that converts the request for the map image into a series of requests for obtaining map tiles. A cache system that stores the map tiles. The tile broker module is operative for returning cached map tiles if they already exist within the cache and retrieving map tiles from the WMS if map tiles are not returned from the cache. A tile building module is operative for building a map image at the WMS proxy from the map tiles in a requested format and resolution and displaying the map image at the client without resampling at the client.</p>
