QGIS WMS Server - QGIS goes Web
This abstract wants to introduce an extended WMS server based on the QGIS 
libraries. QGIS is a user-friendly desktop GIS, which supports various vector, 
raster, and database formats. The new QGIS WMS server executable is a CGI 
application that uses the QGIS functions without opening any GUI. It not only tries 
to implement the OGC WMS and SLD standards – so that it will work with any generic 
WMS client – but it implements also new features. 
One of these new features is the usage of SLD for the configuration/administration 
of layers and styles. An “admin.sld” file, having XML-based syntax, is used for the 
server configuration. The standard SLD elements are extended with new tags which 
describe the data sources and their type. 
QGIS WMS is also trying to implement a basic user authorization by accepting 
optionally two parameters (user and password) over an encrypted connection (HTTPS). 
Based on the user authorization and by providing the possibility of 
uploading/removing layers and styles, the software administration costs and 
deployment efforts will also be reduced. 
Alongside the standard HTTP “GET” and “POST” bindings, also a SOAP binding is 
envisioned. The SOAP binding along with the service description in WSDL will 
support automatic client generation. Additionally, this approach will allow the 
clients to send their data (in GML) as part of the request message. As cartographic 
enhancements of the WMS/SLD standards, new symbolization possibilities like 
diagrams for thematic web maps are introduced.
Beside the presentation of these new features, the talk will illustrate - from a 
technical point of view - the process of transforming an existing desktop GIS like 
QGIS into a functional WMS server.
