基于ArcEngine的林地二类图斑自动编号研究

在森林资源二类调查内业工作中,获取林地图斑面采取了勾绘图斑界线,然后转换为图斑面,最后利用记录属性信息的点状数据对图斑面进行赋值的方法。针对这一流程,利用GIS技术,解决了图斑属性信息记录操作步骤繁多的难题,大大缩短工作步骤,提高了效率。在VB编程环境下,采用ArcEngine组件库,提出利用鼠标图上单击进行记录二类图斑属性信息的算法,通过后台计算自动对属性信息的实施编号。

Research on the Automatic Numbering for Forest Subcompartment Via ArcEngine

In the official work of forest management inventory, to abtain forest subcompartment, wetook to draw subcomparment line firstly. And then converted to subcompartment polygon. Finally,assigned to subcomparment polygon using attribute points. In this process, this paper solves theproblems of the complicated operation steps for subcompartment attribute recording by GIS, andshortens the working procedure greatly, and impoves efficiency. Using ArcEngine componentlibrary under VB coding environment, this paper proposed the algorithm for subcompartment attributeinformation numbering automatically by the use of mouse click on the map. Through the backgroundcomputation, this program can number the attribute information automatically.
