摘要
本文旨在探索一种高效的无林地小班快速定位技术,满足县级林地落界中频繁、快速定位无林地小班的迫切需要,提高遥感判读的效率。在VB编程环境下,采用ArcObjects组件库与数据库技术相结合的方法,提出县域内无林地小班快速定位算法流程,将无林地与有林地边界修正过程中人工繁琐的重复机械操作程序化,实现无林地小班定位的自动化。
This paper explores a rapid positioning technique of non-stocked land with high efficiency. It solves the urgent need of positioning non-stocked subcompartment frequently in county forestland border definition, and speeds up remote sensing interpretation. Combining the ArcObjects component library and database technique under VB coding environment, this paper proposed the algorithm for positioning non-stocked subcompartment. What＇s more, was replaced by program in boundary correction between non - stocked land and forestland, which makes the automatic positioning of non - stocked land subcompartments realized. Artificial tedious and re- petitive mechanical operation by coding, and achieves the automation of non-stocked land subcompartment positioning.
