| 摘 要： | 针对同一空间数据跨不同媒介出版时存在的重复地图制作以及视觉表达效果不统一问题,提出了地图跨媒介出版的概念。通过分析现有地图数据模型,深入挖掘PDF结构中标识内容对象、逻辑结构对象以及可选内容对象等页面内容对象的潜在优势,重点围绕要素对象编码、要素对象结构以及要素分层结构设计了地图跨媒介出版数据模型,该模型突破了过去对满足印刷要求的制图数据和地理空间数据只能分阶段或分模型描述的限制,为地图跨媒介出版数据的存储与管理创造了条件。最后经过试验测试,结果表明了该模型的可行性和有效性。

| Abstract: | Aiming at the problem of repeated map production and differences of visual expression effect appeared when the same spatial data are published across different media,the concept of cross-media publishing of map is proposed.Through analyzing the existing map data models and deeply mining the potential advantages of PDF page content objects such as mark content object,logic structure object, optional content object and so on in PDF structure,the point is around the feature object code,the feature object structure and the feature layered structure launched the design of the cross-media publishing data model of map.The model breached the past limit that the map data which satisfies the printing request and geographic spatial data only can be described on different stages or with different models.It creates the conditions for storage and management of the cross-media publishing data of map.After the experimental tests the results show that the model is feasible and effective. |
