Currently,for the massive multi-source heterogeneous space-time data organization,management,integration difficulties,traditional methods in the data conversion process and other issues caused the data loss,combined with the characteristics of space-time data,this paper presented a new seamless integration of massive multi-source heterogeneous space-time data technology(SIMMHS).The underlying technology for the mass of space-time data and heterogeneous was used FLEX and XML technologies to XML format for data conversion.XML Schema was used to establish a public model,and Virtual Spatial-time Search Engine as an intermediary to achieve platform,realized the massive multi-source heterogeneous seamless integration of space-time data.With the practical application in Shanghai digital ocean demonstration area,integration of the massive multi-source heterogeneous space-time data in effect,facilitate the users browse and query quickly,realized the three-dimensional display of system and real-time update.
