摘要
多光谱遥感数据是沙地动态监测的数据源,从中提取的沙地信息是监测的基础数据。波段是否为最佳组合,直接影响沙地信息的提取和地物的分类。笔者结合研究区域的实际情况,通过对单波段信息、波段间的相关性和OIF指数的分析,研究了提取物及其背景的特征,获得提取沙地信息的最佳波段组合为波段3、4、7。该组合形成的彩色图像地物信息丰富,沙地信息突出,易于目视解译,效果良好。波段的组合研究为后期数据处理提供了有力的技术支撑。
Multispectral remote sensing data is the data source for dynamic monitoring of sandy land. The based data is sandy land information from remote sensing data. Bands selection directly impacts information extraction and land classification. The author applied the bands correlation and the best index OIF index to select optimal bands combining spectrum characteristics of the research objects, finally band 3, 4, 7 were the best combination. This would be advantageous to see and interpret. The study on combination of bands provided strong techniques to support for the post-processing.
