地理对象 meaning in English
geographic object
Examples
- Fuzzy geographical object modeling based on vector data model
基于矢量数据模型的模糊地理对象建模 - The spatial association rule mining module can discover the location association among geographic objects in a map
空间关联规则挖掘模块能够发现地图上的各种地理对象之间的位置关联关系。 - The spatial classification module can classify the geographic objects according to a pre - specified attribute , and the classification result can be used to provide decision support . the classification result can be saved to and loaded from an xml file
空间数据分类模块能够对地理对象按照某个属性分类，利用分类结果为决策者提供决策支持，挖掘结果可以保存在xml文件中或者从文件中读取。 - In addition , the paper designs a bottom database model , selects a multi - aim strategy combining files with known data , and establishes dual interaction data model that has explicit conceptual structure and directly aims to geographic objects , and provides backing up enquiry language ( g - sql ) . simultaneously , after analyzing and studying methods available for the under pipelines , the paper constructs survey adjustment calculation model , and according to the model , checks the survey of under pipelines . the results indicate that the model is suitable to actual requirement because it greatly increase calculation speed , meeting calculation accuracy requirement
在此基础上，对系统的底层数据模型进行设计，选择了文件与成熟数据库相结合的混合策略，并兼顾面向对象的数据库( oodb )和可扩充数据库( edb )的特点，建立了一个概念层次清晰、面向地理对象实体的双层语义数据模型以及支持模型的查询语言g - sql ，同时对地下管线的各种测试方法进行分析研究，建立了地下管线测量平差计算模型，并以此对所勘测的地下管线进行核算，计算结果表明，计算模型不仅大大提高了核算的速度，同时在计算精度上也符合核算的要求，是符合实际要求的关于测量平差计算的模型。
