Spatial information is any type of information that can be spatially referenced and it is widely used in many application domains. Traditional techniques can’t solve the existing application problems of spatial information, e.g. enormous data, format heterogeneity, processing complexity, and wide distribution. Based on the novel technologies that can implement large-scale distributed resource sharing, i.e. grid, Web services and OpenGIS specifications, we propose a new service-oriented application grid named Spatial Information Grid (SIG). System architecture and service-based collaboration are two of the most important research issues of SIG. By building an open SIG architecture, some key theories and methods are discussed in detail to implement service-based collaboration of spatial information. Hence, a novel process model named Service/Resource Net (SRN) is proposed based on Petri net and graph theory, and a dynamic service selection model is presented to select the optimum service. The validity and usability of SIG are verified by an application example in accordance with SIG application flow.Read the full paper here: https://link.springer.com/chapter/10.1007/978-3-540-30466-1_12
