TM遥感影像植被信息提取的最佳波段组合选择——以福建省松溪至建瓯高速公路为例

Optimal Bands Selection of Collecting Vegetation Information in TM Remote Sensing Image——Taking the Expressway from Songxi to Jian'ou in Fujian Province as an Example

以拟建福建省松溪至建瓯高速公路两侧10 km为研究区域,运用最佳指数OIF法,同时参考地物光谱特征曲线以及各波段主要应用范围,在TM遥感影像图植被信息提取过程中,探讨基于遥感技术实现植被信息提取的最佳波段组合,研究显示:145波段组合信息量最为丰富,其波段间相关性最小,为植被信息提取的最佳波段组合.在此基础上,探讨了多光谱数据中,快速、准确选取最佳波段组合,为提高植被解译的精度和工作效率提供重要依据.

Taking 10 km from both sides of the proposed expressway center line from Songxi to Jian＇ou in Fujian province as study area,used the optimal index method of OIF,the spectral characteristic curves and the main usage of the band to study the optimal band combination of the extraction of vegetation information based on remote sensing technology in the TM remote sensing image.The research showed：the 145 band combination is imformative,the correlation between bands is minimal,so it was the optimal band combination of the vegetation information.On this basis,it discussed that the optimal band combination selection quickly and accurately in the multi-spectral data would improve the accuracy of the vegetation interpretation and work efficiency and provide an important scientific basis.
