Before concluding and discussing new perspectives, we propose a brief overview of the cartographic interface to demonstrate how the WikiGIS proposal works. Section 7 is dedicated to the formalization of the WikiGIS concept using UML diagrams.
In Section 6, we propose the “deltification” function as a new means for WikiGIS to allow comparisons between two scenarios. Section 5 deals with data quality issues and, more specifically, the validation and communication of contributions (likelihood level of a contribution). In the fourth section, traceability issues and the conceptual solution adopted are presented. The third section is dedicated to the temporal dimension, since time is a crucial component of WikiGIS. In the next section, we describe the main features of WikiGIS. More precisely, it aims at formalizing the innovative WikiGIS concept from the analysis and testing of the first draft-prototype developed in 2012. This paper is a follow-up to the paper published in 2012. In this study, we define GeoDesign as “art by the creativity of design, and science by the rationale of GIS to improve multidisciplinary group analysis, solution building and decision making with controlled public participation”. We can simply state that GeoDesign describes the integration of GIS and spatial design. However, to date, no consensus has been reached. Since its emergence in 2008, and in GeoDesign summits that have taken place in Redlands every year, many definitions have been given to this new term by a group of thought leaders from academia and a variety of professions. This is particularly the case of Geodesign, a very dynamic emerging field.

Some VGI tools and systems like GeoDeliberator or ArgooMap target professional purposes where a multidisciplinary team (professionals from different domains) must work collaboratively. In the wake of Geoweb 2.0, Volunteered Geographic Information (VGI) (e.g., OpenStreetMap and WikiMapia) and crowdsourced geodata are increasingly being produced by the public, while attracting more and more professionals. Participatory GeoInformation technologies have evolved exponentially and profoundly in the past decade. This interface is simply a means to illustrate the concepts underlying WikiGIS. A user interface is presented later to show how our WikiGIS proposal works.
The core of this paper consists of presenting a conceptual framework for WikiGIS using UML diagrams. One of the main strengths of WikiGIS is its ability to manage the traceability of contributions with an easy and dynamical access, data quality and deltification. It also offers GIS functions for geoprocessing and a design-based approach for sketching proposals. WikiGIS is built on Web 2.0 technologies-and primarily on wiki-to manage the tracking of participants’ editing ( i.e., managing the contributions history). WikiGIS focuses on the needs of GeoDesign, but we leave the door open for future improvement when tested in other areas that may have additional needs.
For this reason, we propose a new concept, “WikiGIS”, designed to answer some dimensions of the GeoDesign process. As an emerging complex concept, GeoDesign requires an innovative theoretical basis, tools, supports and practices.
