摘要
通过分析ESRI ArcGIS输出的地理参考PDF文档格式,明确了如何将地理坐标和特征属性融合到平面PDF格式中,提出了基于PDF规范的地理信息系统实现框架,并分析了框架中涉及主要算法及关键点。最后,借助于Adobe Acrobat API接口实现部份关键算法,以期PDF规范的应用进一步推动地理信息系统理论及应用的社会化和普及化。
Adobe PDF1.7 specification has been recognized as the international document management standard of ISO 32000 for its easy development,cross-platform and security.Socialized Geographic Information System development puts forward the need of using the Adobe PDF specification to distribute geospatial data for non-GIS professionals without professional hardware and software restrictions.Through analyzing ESRI ArcGIS output of the geo-referenced PDF file format,it is specified how to integrate the geographical coordinates and feature attributes into the flat PDF format.Architecture design for Geographic Information System based on the Extended PDF specification is proposed,key algorithms related to the architecture is analyzed,finally realization of algorithms is presented referencing Adobe Acrobat API to achieve that the Extended PDF specification will further promote the socialization and popularization of the Geographic Information System theory and applications.
