Abstract:
Visualisation of spatial information in the form of maps is a critical task to facilitate decision making in environmental management, a task best performed by Cartographic Web Services. An efficient and cost-effective implementation of Cartographic Web Services must rely on existing components. This paper shows how to build such a cartographic
service based on reusable software components and illustates this approach with QGIS mapserver, an advanced Cartographic Web Service built on open-source libraries such as QGIS (Quantum GIS) for map rendering.
QGIS mapserver is a server compliant to OGC WMS (Web Map Service) and SLD (Styled Layer Descriptor) standards and the design of the software allows native support for the concepts of SLD. However, the application of Web Map Services in environmental management usually requires advanced visualisation capabilities which are not (yet) covered by the OGC standards. The implementation of such extensions is possible within the described
architecture. This will be illustrated with the newest developments within the FP6 SANY (Sensors Anywhere) Integrated Project.
SANY aims to create a service architecture capable of providing fast and cost-efficient way to reuse data and services from currently incompatible sensor and data sources. The extensibility of the QGIS mapserver design is exemplified with the implementation of dynamically created contours and raster maps from distributed sensor data.
