| Abstract: | This paper emphatically narrated the building and application of present urban GIS and national spatial data infrastructure. This paper pointed out the building of digital city and UGIS frame system structure was vital role in GIS building. Meanwhile this paper pointed out that National Space Data Infrastructure (NSDI) provided unification, standard geographic foundation platform and the foundation geographic data for various domains. NSDI is of momentous theoretical and practical significance for realizing various domains information sharing and the advancing our country GIS building. |
