摘要
为了提高空间数据的表示和处理能力,对空间对象进行准确的描述是非常必要的。根据空间对象的四类内在属性,设计出了能够准确表达空间对象的空间语义规则。通过用空间本体表示空间数据和用空间分类法对空间数据进行分类,将以往的空间数据处理提升为知识发现,从而提高了空间信息查询的查准率。
To improve the spatial data representation for their subsequent processing,a description for spatial objects is indispensable. According to four types of intrinsic properties of spatial objects,spatial semantics rules were designed which can accurately represent spatial objects. With the spatial data represented by means of spatial ontologies and classified by spatial taxonomies,the spatial data processing can be elevated to knowledge discovery. Thus,the accuracy of spatial information query can be greatly improved.
