This paper proposes a common base‑model for the classical object‑based and field‑based conceptual models in GIS. The authors define the Parameterized Geographic Object Model (PGOModel) using UML and illustrate its use with two extensive examples. The study shows that the PGOModel subsumes both classical object‑ and field‑based GIS models and appears ontologically sound, aside from the PGOAtom concept.
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.
