Abstract
The new century edition of the National Atlas of People’s Republic of China is now being under construction in China. It will reflect social, environmental and economic diversity of China. This atlas is a comprehensive collection of diverse mapping products, including traditional paper version, online version and other information service versions. As a result of the innovative technologies and the usage of new media, online reading is changing, making new demands for online atlas. Online reading demands for reading resource with spatial-temporal and huge information, but the existing online atlas cannot provide enough information. Once published on the internet, the atlas content is fixed. Online reading demands for flexibility reading mode, but the existing online atlas can only be “read”. While the reading atmosphere has changed, the existing online atlas cannot provide enough auxiliary reading tools and knowledge to help readers read map. To resolve this problem, firstly, we introduce the spatial cognition model from cartographers’ and map users’ perspectives and propose a framework for communication model of cartographic information in a web environment. Secondly, based on this communication model, the online atlas is designed, consisting of two parts, which we call the information architecture of online atlas and map reading service. Information architecture of online atlas deals with how to organize and group the maps of online atlas and the contents of the maps. Map reading service is to help map users read, understand and analyze maps. Map reading service includes auxiliary knowledge and auxiliary reading tools. According to different types of knowledge, auxiliary knowledge is divided. According to the different stages of visual perception, auxiliary reading tools are classified into three types: auxiliary “detection" and “distinction" tool, auxiliary “identification” tool and Auxiliary “interpretation” service. Finally, SVG (Scalable Vector Graphics) is used to try out the design.
