Framework and development of digital China

Digital China (DC) has recently drawn much attention. It is a strategic project for China in response to the challenge of sustainable development of population, resource, and environment. Intending to establish the national information infrastructure (NII), the DC project forms a solid foundation for Chinese informatization. In such an NII, multi-sourced spatial data are integrated. They focus on various themes and have different space and time features. Based on the NII, numerous applications and services can be developed so that spatial information will benefit everyone. Since lots of organizations, such as governments, universities, and enterprises, are involved in the implementation of DC, the DC project will significantly prompt the relevant scientific research as well as economic progress in China.
