摘 要:森林资源小班数据编辑是森林资源数据库建立的重要工作,基于Visual Studio 2005开发平台,应用Arc-Engine9.3二次开发组件软件,针对森林资源小班数据的新建立面域、修改与编辑多边形边界,以及因不规则采伐、火烧、病虫害、泥石流、其它工程建设等因素造成的森林资源数据更新等进行了探讨,并提出了方便、快捷、智能的开发方案,从而大大提高森林资源小班面域数据编辑的效率和精度。通过研究,得到如下结论:1)提出了对相邻面域数据无缝构建的新方法,但起始结点和终止结点必须在相邻面区域内;2)提出了相邻面域公共边无缝编辑的方案,主要通过增加、删除、移动公共结点来实现,属性数据不受到任何影响;3)提出了小班面域对象发生变化的森林资源更新方案及试例,包括几何对象和属性数据的更新,从而为森林资源管理提供方便。Compiling sub-compartment polygon is essential for establishing the forest resources database.On the basis of Visual Studio 2005 platform and by use of ArcEngine 9.3 software development module,this study discussed the functions of creation of new polygon and modification and edition for the existing polygon.Furthermore,the functions for the forest updating due to forest logging,forest fire,forest pest,landslide and other project construction,were also discussed,and then the convenient,efficient and intelligent development scheme was proposed.As a result,the efficiency and accuracy of compiling forest sub-compartments were improved.Finally,it was conclude that,(1) The method for seamlessly creating adjacent sub-compartments was proposed under the hypothesis that the start node and end node must be in the adjacent polygons;(2) the scheme for seamlessly compiling the shared border of adjacent polygons was introduced by appending,delete and moving the nodes with the attributes of features unchanged;(3) the updating method and case study for expediently managing forest resources when the sub-compartment was changed by polygon objects,including the geometry object and attributes.
