多元自然灾害信息的空间区位标识与关联调度机制

Aiming at the unified geospatial location identification and efficient location association scheduling of multiple natural disaster information for each disaster area, the unified geospatial location identification model and location association scheduling mechanism based on the global subdivision grid is carried out in this research, along the organization and scheduling process of natural disaster information. First, the unified geospatial location identification model, which is integrated with the spatial scale, spatial location, spatial range and spatial structure (that is spatial geometric form) of a geographic object (such as a disaster area), is established. Secondly, the spatial distribution expression of multiple natural disaster information and disaster information statistics based on the grid unit are explored. Thirdly, the association relationship of the consistent location encoding between the disaster area and multiple natural disaster information is analyzed. Finally, the regional association scheduling mode based on the geospatial location identification is put forward. This research will strive to make some breakthroughs on the theory and practice in the unified geocoding of spatial regional range and position identification and the integration of natural and social data of a geographic object. It will provide the unified coding standard and the intelligent data management and scheduling service for natural disaster information with the geospatial location encoding theory and methods.
