A UML Profile for Conceptual Modeling in GIS Domain

Abstract

Abstract. After many years of research in the field of conceptual modeling of geographic databases, experts have produced different alternatives of conceptual models. However, still today, there is no consensus on which is the most suitable one for modeling applications of geographic data, which brings up a number of problems for field advancement. A UML Profile allows a structured and precise UML extension, being an excellent solution to standardize domain-specific modeling, as it uses the entire UML infrastructure. This article proposes an UML profile developed specifically for conceptual modeling of geographic databases called GeoProfile. This is not a definite proposal; we view this work as the first step towards the unification of the various existing models, aiming primarily at semantic interoperability.
