摘要: 如何提高地质图空间数据库信息交换体系的可扩展性和互操作能力是这一领域中的研究热点.首先研究了ISO/OGC空间信息共享的规范和标准, 并建立了具有服务能力的空间信息集成模块, 在此基础上研究具有一致性的空间信息共享与服务体系, 形成独立于软件、适用于地质空间信息互操作的表达模式, 提供一个可用于异构和分布式体系下的数据描述机制, 使得应用管理地质空间数据成为可能.提出了以地理置标语言(geography markup language, GML) 模型为框架, 给出一种地质空间信息交换的机制.针对地学应用需求, 提出了专业应用数据的模式, 为地质空间信息交换提供了一种可行的方法.Abstract: An approach to geo-spatial information systems considers how to improve expansibility and interoperability, which has become increasingly relevant in this research field.This paper firstly looks at the ISO/OGC rules and standards of geospatial sharing, and then constructs an SOA (service-oriented architecture) geo-spatial integration module.Based on the module, researches the uniform architecture of geo-spatial interoperability and services; forms independent of software and the expression pattern of suit the geological spatial information interoperability.The purpose is to provide a data description mechanism for use in an isomerous and distributing system, making it possible to apply and manage geological spatial data.This paper presents geo-spatial information exchange architecture using the GML (geography markup language) model, aiming at geoscience application demand.The pattern of specialty data is put forward providing a feasible way to ensure geological spatial information interoperability.
