Abstract
This paper proposes a common base‐model for the classical object‐based and field‐based conceptual models in GIS. The model, which is called the PGOModel or ‘Parameterized Geographic Object Model', is given a formal definition by using the UML modelling language. Within the scope of the paper, it has been shown that the PGOModel encompasses the classical object‐based and field‐based models. Two extensive examples demonstrate the application of the PGO model. The PGOModel seems ontologically well founded, except for the so‐called PGOAtom concept.
