Abstract. Volunteered geographic information is constantly being added, edited or removed by users. Most of VGI users are not experts, thus formal representation of spatial data quality parameters through metadata standards does not efficiently communicate, as it may be interpreted differently by different users with different semantics. In addition, a user may not be able to decide on the relevant dataset for their in-hand application. In this paper, we propose providing VGI users with the spatial data quality parameters through simple cartographic representations, which is independent of users’ semantics. The problem is described and its implementation results for a simple case study are represented.
