PHPMyWMS - an open source based, SVG oriented framework for extended Web Map Services

The Web Map Server Implementation Specification (WMS), originally developed and published by the Open Geospatial Consortium, was finally adopted by ISO as an international standard. According to this standard maps are presented either in "picture" formats or "graphic element" formats. While the pictorial (visual) representation uses raster formats, graphic element formats include Scalable Vector Graphics (SVG) or Web Computer Graphics Metafile (WebCGM) format. In this paper a framework for supporting Web Map Services using SVG will be presented. Geo-data, converted to SVG, is stored in a database management system, retrieved by the WMS server upon user request and transferred-optionally compressed-through the Internet. Finally it is visualized in Web browsers on desktop computes or mobile devices, natively or using plug-ins extending the browser's functionality. Besides supporting the WMS request GetCapabilities, GetMap and GetFeaturelnfo requests, additional formats and extensions have been included in this framework. The development proves that open, XML-based standards in combination with modem programming languages and integrated development environments allow rapid implementation of recommendations and standards in geo-informatics.
