Abstract:
With the development of global economy and society, international spatial information is needed by community increasingly.The features and sources of dynamic heterogeneous space information are analyzed and, on such a basis, organizational rules of spatial data are established.Using international place names identification and content integration technology, tens of thousands of users' collaboration plotting, dynamic heterogeneous spatial information storage technology based on virtual resource pool, adaptive display of spatial data and mechanism of breakpoint continuingly element level data updating, the authors prototyped the method of massive global dynamic heterogeneous spatial information real-time/near real-time access.The design and research results show that the real-time access technology for massive dynamic heterogeneous spatial information solves real-time transmission of plotted information, realizes the real-time/near real-time display of plotting data on multiple scales and ensures the real-time and readability of massive spatial information resources and services.
