摘要
如何通过定量计算选择最佳波段组合一直是TM等多波段遥感影像信息提取的研究热点。本文综合利用Erdas提供的可视化空间建模工具(Spatial Modeler)和面向对象的编程技术,提出了一种基于最佳指数(Optimum Index Factor,OIF)的定量计算与定性分析相结合的TM遥感影像最佳波段组合方法。实验证明,该方法快速有效,极大提升了TM等多波段遥感影像最佳波段组合的计算过程。
How to choose the optimum band combination by quantitative computation has always been a research hot spot of TM multi-band remote sensing image information extraction .Trough integrated using visual spatial modeler provided by Erdas and oriented -object programming technology , this paper proposes a method to select optimum band combination quantitatively and qualitatively for TM remote sensing image based on Optimum Index Factor ( OIF) .Experience has shown that this method is fast and effective to pro-mote the computing process of optimum band combination of TM remote sensing image .
