| 摘 要： | 基于制图综合知识的空间数据检查是GIS和制图综合中迫切需要研究的问题。首先,分析数据检查的重要性和制图综合知识在数据检查中的作用。其次,对制图综合知识的归纳进行阐述:在分析国内外研究的基础上,定义一套基于模糊型知识和精确型知识为基础的知识分类模式;并据此提出一种制图综合知识的结构化描述方式;然后提出知识属性的概念,阐述知识属性在知识中扮演的重要作用,定义知识属性的详细指标。第三,进行基于制图综合知识的数据检查:在对数据进行重要性排序的基础上,提出基于模糊型知识的人机协同的数据检查方法,和基于精确型知识的自动数据检查方法,并给出详细的数据检查程序流程。最后,给出相应的例子。从数据检查的结果来看,提出的知识归纳方法能够满足当前制图综合的多种需求,基于知识的数据检查方法能够为进一步实施制图综合提供强有力的信息和依据。

| Abstract: | Spatial data checking with generalization knowledge is an exigent problem to be researched in GIS and cartographic generalization.Firstly,analyze the importance of data checking,and the effect of generalization knowledge on it. Secondly,expounding the process of summarizing generalization knowledge.After analyzing this field's current research,a classifying knowledge model based on fuzzy knowledge and accurate knowledge is defined.Based on the above,a generalization knowledge structure is put forward.Then,a concept of knowledge attribute and its particular targets are brought forward which is important during using generalization knowledge.Thirdly,introducing the whole process of data checking based on generalization knowledge.After ordering the sequence of data layers by weightiness,a synergic data checking method based on fuzzy knowledge and an automatic data checking method based on accurate knowledge are created.With these methods,generalization tasks are described as generalization flow-programs,which can be executed by computers.Lastly,an example is shown.Its result illustrates that each of the cartographic generalization's needs is satisfied with the data checking model introduced above.This checking method with knowledge can provide valuable information and the gist for generalization operation and process. |
