摘要
在分析和借鉴传统的水深综合理论和方法的基础上,开展水深数据的层次性分析,对水深数据进行分类、定级和聚合等处理方法研究。在满足制图综合规范的基础上,按照水深分类数据的重要性和特征性排序,重组综合方法使用顺序和结构,从而构建层次水深综合模型。该模型能够实现水深综合的流程控制,兼顾水深综合的质量要求,为进一步开展水深自动综合的实用性研究提供了理论和技术支持,具有一定实用价值。
Based on analysing and referencing the traditional theories and methods of sounding generalizations,we analyse the hierarchy of the sounding data,and study the methods of classification,grading and polymerization for sounding data.On the premise of meeting the specification of the cartographic generalization,we arrange the classification of sounding data based on the significance and character,and reform the employed gradation and structure of generalization methods,then build the mode of sounding generalization based on the hierarchy.This model can achieve the process control of the sounding generalization,and cares the quality requirements of the sounding generalization,so this text can offers the support of theories and techniques for the further applicability of the automatic sounding generalization,with a certain pragmatic value.
