1. Overall design for “The Electrical Atlas of Regional Development in China” (“E-atlas” for short)

The contents and expressions of “E-atlas” are determined in terms of the study of regional development. The visual expression of regional development phenomena: Use positioning point symbols and statistical tables and graphs to express the elements of regional development. Using points, lines and polygons expresses the structural adjustments and developmental patterns. The correlations among objects were described based on the inside and organic connection among population, economy, city, resource, environment and regional development from different aspects. According to the results of analysis and synthesis, the situation of present and future, the different levels of description and evaluationthe atlas contains analytical maps of single element or multi-element which can be used to evaluate and forecast developments. The atlas has multilevel dimensions.

2. Design for topic of “E-atlas”

There are lots of issues about resource, environment, society and economy caused by regional development. “E-atlas” integrally describes these issues on aspects of history, present and the future. “E-atlas” reflects features of regional development in China and also pays special attention to the special problems of regional development and sustainable development. “E-atlas” reveals the regulation of regional development in China.

3. The framework of “E-atlas”

The framework of “E-atlas” not only reflects the whole character of map region but also reflects regional peculiarity.

“E-atlas” is built on the study of economic development, social development, natural resources and ecological environment. There are several sub-topics under each topic, and each sub-topic was displayed by several maps. With this structure, “E-atlas” is systematic.

“E-atlas” mainly composed of four modules of electrical mapmaking system, map management system, map browse system and regional development database querying system.

4. The structure of “E-atlas”

According to the rule of regional developmental, the content of “E-atlas” contains four parts: economic development, social development, natural resources and ecological environment. The “E-atlas” consists of 11 map groups: map groups of preface, economy, external trade, industrial development, agricultural development, infrastructure, population, urban construction, people's lives, resource and environment and sustainable development.

5. The function of “E-atlas”

“E-atlas” can be read in computers directly and display maps on the screen. User can inquire catalogue, display maps, zoom in or out, browse map, inquire interested property, search by expression, analyze the model of regional development and read supplementary explanation via person-computer interaction. The function of spatial analysis: The analysis of regional economic developmental based on statistic data could be made, and the result for space-time variety rule could be expressed in electrical map.
