Data Sharing of Digital Basin Based on GML

摘要

The data for establishing digital basin has the features of large quantity, heterogeneity and multiple dimensions. Determining how to effectively manage and share the data is the key for digital basin. This paper shows an information sharing model for digital basin based on metadata directory, Service-Oriented Architecture (SOA) and publishing/subscription technology. And then, for easily transmission, we preliminarily accomplish the data conversion based on Geography Markup Language (GML).
