In order to identify spatial information's area coverage and spatial position in a globally unified and multi-scale way, a kind of spatial information location identification coding model based on the geographic coordinate subdivision grid with one-dimension-integral coding on 2n-tree (GeoSOT) is presented. By means of the globally fixed grid division and structural grid representation, the GeoSOT-based model adopts a triple (C0, M, N) that integrates the geospatial orientation, scale, range and structure in to one set to describe five kinds of location information belonging to a same geographic object, such as the geographic object's area coverage and spatial position, internal spatial grid, spatial point-line-area entities, spatial attribute information, and spatial information network domain. By the comprehensive design of the methods for this location identification's coding definition, generation and application, the model can make it possible to achieve a consistent location association relation of the multi-type spatial information that belongs to a same geographic area, and provide a unified geocoding reference for the management and application of global multi-type spatial information.

To better improve the emergency communication and location-based services of disaster information reporting network for serious natural disaster emergency response and relief, the national natural disaster reduction application platform based on BeiDou navigation satellite system is constructed. The administrative distributed platform is integrated with BeiDou positioning and multiple communication ways so as to achieve main disaster reduction application services, including disaster information acquisition and monitoring, emergency relief for trapped people, on-site emergency relief command service, relief supplies' transportation monitoring, and disaster information publishing service. By the platform, serious disaster information reporting time may be reduced to one hour and the emergency decision-making information service for serious natural disasters can be effectively improved, and it will be helpful to provide technical references for the industrial application and promotion of BeiDou integrated disaster reduction. © 2013 IEEE.
