一种改进的线状分布图斑自动编号设计与实现

Design and implementation of an automatic numbering method for linear distribution polygon based distance of on broken line

线状分布图斑的坐标没有规律性,无法按传统的上北下南、左西右东的方法进行编号,自动编号方法一直是林业工作的一个难点之一。对现有的编号方法进行了探讨和分析,以图例方式详细阐述现有方法的不足,并在现有方法基础上,提出一种改进的、按折线距离远近对线状图斑进行编号的方法,避免了现有方法的不足,并用C#和ArcGIS Objects实现了线型分布图斑自动编号工具,工具能较为准确、快速地为线状分布图斑进行编号,初步解决线状分布图斑自动编号的问题。

Because the coordinates of linear distribution map are not regular,it can not be numbered according to the traditional method of coordinate value.The automatic numbering method is one of the difficulties in forestry work.Firstly,this paper discusses and analyzes the existing numbering methods,and expounds the shortcomings of the existing methods in detail in the form of illustrations.Based on the existing methods,an improved method of numbering linear patches according to the distance of broken lines is proposed,which avoids the shortcomings of the existing methods,and the automatic numbering tool of linear distribution patches is realized with c#and ArcGIS objects.The tool can number the linear distribution spots accurately and quickly,and preliminarily solve the problem of automatic numbering of linear distribution spots.
