网状径路计算基点基线参数自动形成的研究

网状径路里程计算是铁路运输费用计算中不易解决的问题,其主要难点是运算中所需矢量数据量大而且具有整体性,局部变化会引起整体数据格局的变动,人工难以输入及维护;不能在基点、基线的矢量数据基础上直接运算."自动矢量处理"实现了在自然数据基础上网状径路数据自动产生、快速运算.数据维护一般操作人员即可完成,速度可达到一次直接运算.

Automatically Generated The Parameter of Reticulation Route Calculated Base Point and Base Line

Creating the parameter of reticulation route data by using the way of automatic vector processing Calculated the mileage with reticulate route is the masty difficulty in course of calculated railage.because there is a large quantity of the data needed in the process of calculated ,and these data are impartibility.If the data has a little change ,there will be a large change in the whole data struction.to solve this with manpower is difficult,and it is difficult to directly operate with vector data of base point and base line. The way of automatic vector processing accomplishes automatically generation of reticulation route data and quick operation . Primary operator can easily maintain the data and the speed of operation is high. This artical will briefly illuminate the data structure which is necessary in the process of calculated and the data processing couse.
