Large format maps on the Internet

Production of maps in large format directly from the Internet can be useful for several areas, such as for producing printed maps or supporting map information in offline applications. The WMS standard has simplified the availability of online maps. However, WMS servers usually have a limitation in image size for the GetMap response. To enable large formats, the initial requests have to be split into several and smaller requests that comprise the whole area. Client-based techniques in the assembling process are described. The quality of such maps can be limited in some cases, but the products resulting from these techniques can still be sufficient for a wide range of applications.
