This paper investigates one dimension of VGI use that has received relatively little attention to date, namely the influence of different cartographic visualisation methods on citizens' ability to explore and understand VGI. Following a brief review of key challenges related to VGI use, the paper describes a web-based software prototype that was designed to allow users to compare several simple geovisualisation and data filtering techniques for VGI exploration. Next, attention is directed to a specific study context where citizens used the software tool to explore a rich data set of locally-produced VGI related to community assets. The paper concludes with a discussion of the results from this experiment.

Potential of VGI as a resource for SDIS in the north/south context / E. Genovese in Geomatica, vol 64 n° 4 (December 2010)  

Public [article]  inGeomatica > vol 64 n° 4 (December 2010) . - pp 439 - 450 Titre : Potential of VGI as a resource for SDIS in the north/south context Type de document : Article/Communication Auteurs : E. Genovese, Auteur ; Stéphane Roche, Auteur Année de publication : 2010 Article en page(s) : pp 439 - 450 Note générale : Bibliographie Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Infrastructure de données [Termes IGN] données localisées des bénévoles [Termes IGN] infrastructure nationale des données localisées [Termes IGN] intégration de données Résumé : (Auteur) New on-line services that support user generated and user modified maps are emerging at a rapid pace and a vast amount of information has been created. Anyone with Internet access via computer or mobile devices now has the ability to display geospatial data and voluntarily add information without the help of a GIS expert. This user created geospatial content has been named Volunteered Geographic Information (VGI) by Goodchild [2007a]. The concept and its implementation present a combination of potential and risks, which now must be considered. This study aims primarily at detecting, and presenting schematically, the strengths and weaknesses, opportunities and threats of VGI as a resource for Spatial Data Infrastructures (SDIs) in the North and South contexts. We explore how the integration of VGI with official information can be a powerful source of novel data that can be included in SDIs. We analyse the VGI potential in developing countries, especially in areas where reliable spatial data is scarce and the digital divide is more delineated. We suggest that the use of VGI technology can be capitalised upon by building SDIs, and we conclude with a number of suggestions for further research.
