北京城市记忆照片资源地理空间化组织平台构建

Construction of Beijing Urban Memory Photograph Resources' Geospatial Platform

城市记忆资源是留存城市历史,传承传播城市文化的重要资产,其中的照片资源则能较为直观地体现城市历史风貌变迁,这些资源被分散保存在档案馆、图书馆等机构以及私人手中,本研究将分散的照片资源集合,引入GIS地理信息系统,实现照片资源与地理信息的映射,将照片所反映的人物、事件、时间、地理聚焦在方寸之间.同时参考DC与VRA元数据标准,根据实际需求设计出一套照片资源的元数据方案,并制定了四层分类体系.利用该元数据方案和分类体系,系统中著录了大量历史照片资源,并以瀑布流和时间轴的形式向用户呈现.最后,融入Web2.0思想,开发出一个界面美观、用户友好、访客参与的可扩展、可通用的历史图片多维组织展示平台,力求通过影像展示传播老北京文化积淀与精神财富.

City memory resources are important assets which enable us to preserve histories and pass on cultures. In terms of photograph resources amongst them, they can help to present city＇s historical and cultural changes directly. These resources scatter around and are preserved in various places, by different groups such as archives, libraries and individuals. This research combines decentralized photographic resources with Geographic Information System （GIS）, focusing on the figure, event, time and location of the photos to map them with geographic information in webpage and to display them productively. In order to meet the demand of reality, a metadata description proposal is designed, referring to DC and VRA standards. Another essential procedure is to formulate a four-tier classification system to correspond with the metadata proposals. As for visualization, we use Photo Waterfall and Time Line to display our resources in front end. Last but not the least, led by the Web 2.0 trend, we exploit an artistic, friendly, user involvement, expandable, and general historical display platform to show the historical and culture precipitation of Beijing.
