摘要
为解决海量大比例尺地形图批量快速自动接边问题,本文总结了现有接边算法优缺点,并在其基础上进行改进,提出一种优于目前接边算法的海量多种类数据自动接边方法,并对该方法关键部分进行了详细阐述。为减少对外部类库的依赖,采用Visual Studio开发环境实现算法,不依赖外部组件。将开发的接边工具应用于全国5万比例尺数据改化项目的实践证明,该算法可有效解决海量数据快速接边问题,提高了接边的效率。
In order to solve the problem of rapid automatic edging of massive large scale topographic maps,this paper summarizes the advantages and disadvantages of existing edging algorithms,and makes improvements on the basis of them.A new method of automatic edging of massive and multiple kinds of data is proposed,which is superior to the current edging algorithm,and the key parts of this method are described in detail.In order to reduce the dependence of external class library,Visual Studio development environment is used to implement the algorithm,which does not depend on external components.The application of the developed edging tool in 50000 scale data transformation project proves that the algorithm can effectively solve the problem of rapid edging of massive data and improve the efficiency of edging.
