Geographic information (geo-data; i.e., data with a spatial component.) is being used for civil, political, and commercial applications. Modeling geo-data can be involved due to its often very complex structure, hence placing high demands on the modeling language employed. Many geoapplications would greatly benefit from the possibility of integrating existing geo-databases. Data integration is a notoriously hard problem, and integrating geo-databases in practice often adds the extra requirement that the integration should result in a real-time system. This paper provides a case study and a design method for real-time integration of geo-databases based on the ORM modeling language. We will show that the use of ORM is superior to competing approaches, and that the so-called ORM federation procedure will yield correct design of integrated geo-databases.
