Study on the Data Model of Digital Map Product

Mechanization is the characteristic of the industrial era and computerization is the characteristic of the Information Era. Now we are facing on the transition from Industrial Era to Information Era. The spatial positioning character of Geo-spatial information is attracted by Information Technology (IT) industry. Map plays an important role in the phylogeny of humankind. Concomitance with the development of the implementation, the advance theoretic and technology has been much involved in Cartography. Therefore, the data source, the material, the tools, the methodology, the production process, the formation of map making and even the needs of the map user are greatly changed in 20 century. This paper base on the concept and principle of topographic map, designed a new digital Map Product Model to satisfy with new requirements of the map users.
