摘要
针对空间信息的区域范围和位置标识的统一性和多尺度性问题,基于2n一维整型数组的全球经纬度剖分格网(GeoSOT)框架提出了一种具有全球统一性、多尺度性和结构性的空间信息区位标识编码模型.该区位标识编码模型通过将球面固定格网剖分的空间定位、空间尺度、空间范围和空间结构集于一体的三元组(C0,M,N)来对同一地理对象的区域范围与位置、内部空间区域格网、空间点线面实体、空间属性信息、空间信息网络域五种区位信息进行统一描述与一致性表达.通过对区位标识编码定义、生成方法及应用方法的综合设计,可实现同一地理区域的多元空间信息之间形成一致性区位关联能力,为全球多元空间信息的统一管理和应用提供统一地理编码参考.
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.
