Overcoming the semantic and other barriers to GIS interoperability

TLDR

Many applications require accessing data spread across multiple independent GIS, prompting extensive research into interoperable information systems and diverse interpretations of interoperability. The paper identifies challenges for the next generation of interoperable GIS and proposes solutions to address them. The authors review current efforts, provide a concise definition of GIS interoperability, and present a proposal to meet the identified challenges.

Abstract

An increasing number of applications need to work on data that are scattered over several independent geographical information systems. This has led to extensive research efforts in the field of interoperable information systems. The term interoperability is used in a number of different contexts. In this paper a concise explanation of the meaning of interoperability in the context of GIS is given. Current efforts in this realm are presented. Problems and challenges of the next interoperable GIS generation are identified. A proposal to meet these challenges is presented.
