Abstract
In this paper, we present a visual language dedicated to spatial data called Lvis. This language has been defined as an extension of the Cigales visual language based on the Query-By-Example principle. The language is based on predefined icons modelling spatial objects and operators which are used to build a visual query. The visual query is then translated into the host language of any Geographic Information System (GIS). A major problem of such a language is that visual queries are generally ambiguous because of multiple interpretation of the visual representation. We first present a brief state of the art of languages dedicated to GIS and then formally define our visual language. The global architecture of the system is described. We then focus on visual ambiguities and propose a model of detection and resolution of these ambiguities.
