基于网络GIS技术的时空典藏整合环境构建

The Construction of the Spatial- Temporal Contents Integrated System Basing on Net GIS

时空信息是所有内涵数据都具备的基本特性,通过时空信息处理技术建构时空坐标体系,让所有数字典藏的内容得以整合,通过网络开放式交换机制,让原本储存在不同机构的信息,既可以分散储存,又可以彼此引用套合,促成信息统整。本文探讨了利用互联网地理信息系统建构数字典藏计划的时空内涵基础架构,其最主要目的在于扩充原有地理信息系统内涵,发展成时间及空间信息处理技术,建构起时空内涵基础架构,以精确的时空参考系统为基础,建立所有典藏内涵的时间与地理空间标记(geographic footprint),做为信息检索和信息整合的主要依据,并以空间可视化(Spatial Visualization)方式提供更生动、易读的、精准的事件原貌。

Spatial - Temporal information that is all the content data are available in the basic characteristics, through the spatial and temporal information processing technology construction of time -space coordinate system, let all the digital archives of the content can be integrated, through an open network exchange mechanism, let originally stored information in different institutions can distributed storage, and can refer to each other is sheathed, contributed to the integration of information. This paper explores the use of internet geographic information system construction of Digital Archives Program spatial - temporal intension infrastructure. Its main objective is expanding existing geographic information system connotation, development into temporal and spatial information processing technolo- gy, constructs the spatial -temporal intension infrastructure, with precise temporal and spatial reference system as the basis, the es- tablishment of the connotation of all collection time and geographical space markers （ geographic footprint）, mainly on the basis of in- formation retrieval and information integration, and provide more vivid, readable, and precision of the events of the original （ Spatial Visualization） in visual space.
