中国将时空信息列为重要的新型基础设施,如何有效提供地理信息服务,是发挥全球时空信息基础设施效能的关键。传统空间数据基础设施(spatial data infrastructure
SDI)正面临着服务内容与服务技术的变革。结合地理信息两大标准化组织国际标准化组织(international organization for standardization,ISO)/TC211和国际开放地理信息协会的地理信息服务实践,提出新一代国际地理信息服务体系总体框架,涵盖服务分类、服务接口、服务架构、服务元数据、服务实施5大核心内容,通过技术解耦与依赖分层,增强体系的可扩展性与可持续演进能力。在此基础上,总结当代地理信息服务系列技术标准,提出服务标准制定实施指南,为全球ISO 19119地理信息服务体系标准修订提供理论方法支撑。
Objectives
2
Geographic information services (GIServices) are a key enabler for realizing the full potential of global geospatial data and information infrastructures. There are significant efforts on the development of spatial data infrastructures (SDIs) to deliver efficient GIServices
which in turn have led to the evolution of an international service infrastructure that guides the development and standardization of geospatial services across countries. Traditional geospatial services in SDIs are enriched with more content and advanced technologies. There is a need to propose a new-generation framework for geospatial services.
Methods
2
Building upon the geospatial service design defined in international organization for standardization (ISO) 19119:2016
and incorporating the latest advancements in service technologies
we extend an overarching framework for an international geospatial service infrastructure characterized by technological decoupling and layered dependencies. This framework encompasses five key components: service taxonomy
service interfaces
service architecture
service metadata
and service implementation. Based on these core components
the connotation of geospatial services and their standard design are systematically elaborated.
Results
2
A resource-based geospatial service taxonomy is introduced
comprising geographic sensing services
geographic discovery services
geographic data services
geographic processing services
geographic visualization services
and geographic knowledge services. This service taxonomy is compatible with geospatial artificial intelligence (GeoAI) technologies
thereby enabling the provision of GeoAI services. The abstract interface model of GIServices is presented
encompassing components including interfaces
operations
parameters
and operation chains. Methods for achieving syntactic and semantic interoperability among interfaces are also elaborated. An abstract interface can be mapped to different service architectural styles. Such mappings need to take into account the representation of service interfaces
payloads and protocols
as well as message exchange patterns. The mapping approaches for the two mainstream architectural styles of GIServices
service-oriented architecture and resource-oriented architecture
are presented. The GIServices metadata model defined in ISO 19119/19115-1 is refined by decoupling it from the abstract interface model
enriching it with service descriptions and fundamental attributes
and incorporating quality of service. A service development procedure is proposed
which maps from technology-neutral unified modeling language to specific data encodings
communication protocol bindings
and particular development languages and frameworks. Additionally
intelligent GIServices implementation based on agents for service chaining is also introduced. Based on the key content mentioned above
a multi-tiered geospatial information service standards framework has been suggested
encompassing fundamental service standards
platform-neutral standards
platform-specific standards and service metadata standards. A practical guideline for developing service standards is proposed.
Conclusions
2
The five components of the service framework are fundamental for developing an infrastructure of geospatial services. It also provides the guideline on setting up new geospatial service standards. The design rationale depending on the technical decoupling and multi-layer dependencies ensures scalability for future technologies. The work provides the methodological foundation for the new version of ISO 19119 series standards.
