چکیده
Abstract. With the wide application of Big Data, Artificial Intelligence and Internet Things in geographic information technology industry, geospatial big data arises at historic moment. In addition to traditional "5V" characteristics data, which are Volume, Velocity, Variety, Veracity Valuable, also has "Location Attribute". At present, study mainly concentrated in: knowledge mining discovery Spatiotemporal mining, impact on visualization, social perception smart city, services for government decision-making support four aspects. Based connotation extension this paper comprehensively defines comprehensively. The location industrial thematic comprehensive service science is introduced detail. Furthermore, key technologies design indicators National Geospatial Data Platform elaborated from perspectives infrastructure, functional requirements non-functional requirements, Public Service illustrated. challenges opportunities discussed open resource sharing, management decision security. Finally, development trend direction summarized prospected, so as build a high-quality platform play greater role public administrative decision-making.
