It involves the exchange of information among different systems, and requires agreement on formats and application domain concepts. Interoperability may also encompass commonality of user interaction and system behavior. One of the interoperability problems which has been investigated for over 20 years on different contexts is that of integration of heterogeneous data. However, even this fundamental and old problem is very hard to solve. The data integration problem may be considered from many perspectives and on increasing levels of complexity or abstraction. This paper reviews the literature about interoperability in general, and integration of heterogeneous geographical data in particular, presents several facets of the data integration problem, and some approaches to deal with them. aDados geográficos heterogêneos aHeteregeneous geographical data aInteroperabilidade
