摘要
针对森林资源清查样地样木位置图绘制现状,探索样木位置图自动成图技术,提出开发样木位置图自动成图软件,以期为提高工作效率和成果质量提供技术支撑。程序将样木位置信息封装在CTree类中,使用ADO实现了对数据库的播入、更新,并通过GDI对象封装绘图函数实现样木位置图的自动生成。
Drawing status quo of sample tree position map in forest resource continuous inventory,the automatic mapping technology has been studied and the software also been developed to improve the efficiency and quality of results and provide technical support. The program packed the sample tree position in CTree class,using ADO to achieve the input and update of database,finally,by taking drawing function of GDI,sample tree position map was automatically made.
