“数字中国网”的构想与设计

CONCEPTION AND DESIGN OF “DIGITAL CHINA NETWORK”

随着空间信息应用深度和广度的扩大,对各类空间信息资源的需求将日益增长。传统的空间信息应用模式越来越难以适应空间信息服务网络化、业务化和产业化的发展趋势。在分析当前对地观测技术发展和空间信息应用需求的基础上,借鉴电子商务平台的模式理念,将交易的理念引入到空间信息资源的开发利用中,提出了建立数字中国网的构想。通过实现数据/信息产品、定制服务、应用系统集成和数字工程实施的业务化运营,盘活空间信息资源、实现空间信息服务的工程化和业务化。同时根据提出的构想,设计并初步实现了基于"B/S+G/S"混合模式的数字中国网的构想方案。

With the enlargement of the depth and width in spatial information applications, the requirement of all spatial information resources will be ever increasing. Traditional spatial information application mode becomes more and more difficult to adapt to the development trend of the networking, operationalisation and industrialisation of the spatial information services. Based on analysing the development of earth observing technology and the requirement of spatial information application, we learn from the mode and idea of e- commerce platform, introduce the transaction idea into the development and utilisation of spatial information resources, and propose a conception of building the digital China networks. By putting the data and information products, customised services, application system integration and digital engineering implementation into operational use, the spatial information resources can be liquidised, and the spatial information services will be put into engineering and business. At the same time, according to the conception proposed, the conceived scheme of digital China network based on B/S and G/S model is designed and implemented initially as required.
