Digital China Geo-spatial Framework Construction: Situation, Problems and Suggestions
Under the background of Digital China geo-spatial framework construction(DCGSF), the paper elaborates on the fundamental data system, data clearinghouse and web service system, law/policy/standard system and organization system. National geodetic datum plays an important role in keeping geo-spatial information onto a unified base, while national geographic databases are the main body of DCGSF. Data clearinghouse and web service system is not only an important component of DCGSF, but also an important component of National Spatial Data Infrastructure (NSDI). In order to secure and promote DCGSF process, Law, policy, and standard system and organization system should be paid enough emphasis. As to some problems concerning geo-spatial framework construction emerged, five suggestions are given.
