Interoperability is one of the most important challenges related to GIS. Through the last years, research on interoperability has evolved from the simple off-line exchange of standardized-format files, through the establishment of spatial data clearinghouses, and to the first initiatives in the treatment of semantic aspects of data. The Open Geospatial Consortium (OGC) has proposed a number of standards to that respect, with the intention of promoting interoperability through the use of services. However, issues regarding fault tolerance, server-independent implementation, delayed-time transactions, privacy, and others reflect the need for further study and discussion. This paper discusses the current status of service-oriented architectures as applied to interoperable GIS, or, more specifically, to the implementation of Local Spatial Data Infrastructures (LSDI).
