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