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.

Key words: PDF, GIS, cross-media, feature layered object
