Abstract: First of all, this paper analyzes the disadvantages of traditional thematic mapping technology in the development of surveying and mapping information. And then, based on the rapidly developing WebGIS technology, we explore the online mapping technology based on Web services, and propose the interactive custom mapping based on online map from the aspects of symbol construction, mapping service model, data service and so on. Finally, an interactive cartography system based on Web services is designed and developed, which realizes online subscription cartography for ordinary users and online customization cartography for professional users. Our practice shows that the dynamic thematic mapping system is flexible in function, diverse in expression and high in communication efficiency, and can meet the needs of users with different backgrounds.

Key words: WebGIS, subscription, customization, thematic map, map expression
