摘要
动态分段技术是一种新的线性特征的动态分析、显示和绘图技术。本文对动态分段数据模型进行探讨,提出一套基于动态分段技术构建河流数据模型的实现方法,它解决了传统数据及属性管理和分析中一对多、线性度量以及分段数据等难题,为水务普查成果数据的管理和分析提供了一定借鉴意义。
The dynamic segmentation is one kind of new technology with that linear feature can be ana- lyzed,displayed and mapped dynamically. The paper discusses the data model of dynamic segmenta- tion, and presents a expression method of river based on dynamic segmentation, It addresses the problems in the management of traditional data and attributes, such as one to many, linear measurement and segmentation data. It provides a reference to management and analysis for water census data.
