USING SDI-BASED PUBLIC PARTICIPATION FOR CONFLICT RESOLUTION

Web-based tools for public participation using maps, often referred to as public participation GIS (PPGIS), gain importance as the Internet becomes a commonly available source of information. E-government finds its way into town halls, and both citizens and municipalities begin to benefit from the low costs and the convenience of the web. Moreover, public participation has been fostered as a main concept for sustainable development by several international agreements throughout the past years, such as the European Commission’s Directive 2003/35/EC (European Commission 2003) or the United Nations’ Agenda 21 (United Nations 1992). Although PPGIS have been a hot research topic for almost a decade, we are still waiting for the breakthrough of applications in this field. This paper delineates the way from the existing, mostly monolithic and non-interoperable tools to service-oriented, reusable applications, using the development of the Argumentation Map prototype as an example. Generally, spatial data infrastructures (SDIs) should provide a suitable environment for the integration of PPGIS; we will discuss the suitability and sufficiency of currently used standards for this special SDI use case.
