As an important value-added function for GIS service, GIS service chain provides the application foundation for reusing and automation composition GIS services. An important issue for realizing the value-added service is ensuring the operation results of GIS service chain meet the user needs, so it needs to verify the correctness of GIS service chain. This paper introduces the equivalence theory of Pi-calculus. A practical GIS service chain formal model is established using Pi-calculus. The validity of GIS service chain model and whether it meets the need are verified using the formal tools.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
