Abstract: The emergence of Web 2.0 is materialized by new technologies (APIs, Ajax ...), by new practices (mashup, geotagging ...) and by new tools (wiki, blog ...). It is primarily based on the principle of participation and collaboration. In this dynamic, the web mapping with spatial character or simply called Geospatial Web (or Geoweb) evolves by strong technological and social changes. Participatory GeoWeb 2.0 is materialized in particular by mashups among wikis and géobrowsers (ArgooMap, Geowiki, WikiMapia, etc.). The new applications resulting from these mashups are moving towards more interactive forms of collective intelligence. However, these applications do not take into account the collaborative work or the traceability management or the dynamic access to the history of contributions. The Geodesign is a new area, which is the coupling between GIS and design, allowing a multidisciplinary team to work together. As it is an emergent term, the Geodesign has not be well defined and it requires innovative theoretical basis, new tools, media, technologies and practices to fit its complex requirements. We propose precisely in this thesis new features of WikiGIS, which is built on Web 2.0 technologies, and GeoWeb 2.0 aiming in particular to support the collaborative dimension of Geodesign process. The WikiGIS consists of wiki features for the geospatial data (including its geometric component: shape and location) to ensure, dynamically, the documented release management objects and access to these versions (and metadata), facilitating collaborative work on Geodesign. It aims to produce geographic information, while ensuring the quality and credibility of data created. We propose the “deltification” as one of the innovative features of WikiGIS, it is the ability to compare and display the differences between two versions of a project. Finally, the relevance of some geoprocessing and "sketching" tools is mentioned. The main contributions of the present thesis are firstly identifying the needs, requirements and constraints of collaborative Geodesign process, and secondly to offer new features of WikiSIG best meeting to the collaborative dimension of this process. For this, a theoretical framework is drawn up which we identified the requirements of the collaborative Geodesign process and we proposed some innovative features that are subsequently formalized by UML. A user mock-up is developed in order to show the WikiGIS features, which are illustrated on a simulated case study, treated as proof of concept. Finally, these concepts are ultimately validated by experts through a questionnaire and interviews. Briefly, we have amply demonstrated in this thesis the importance of traceability management and how to dynamically access in the historic of Geodesign process and we have proposed other features like deltification, multi-media component that supports the arguments, parameters describing the data produced, decision making by consensus, etc.
