基于不同空间信息源的地物光谱反射率模拟图像分析

Analysis for features spectral reflective ratio simulated images on different spatial information sources

本文利用ERDAS Imaging软件中的Modeler模块,开发了地物光谱反射率图像的模拟技术。以野外实测地物光谱反射率数据为依据,用土地利用类型图和高分辨率遥感影像图作为地物空间分布的信息源,以陆地资源卫星TM1-4波段为例,模拟了4个波段的地物光谱反射率图像,合成了真彩色和标准假彩色图像。对基于不同空间信息源的地物光谱反射率模拟图像进行了对比分析,指出了进一步研究的方向。

The simulating method of features spectral reflective ratio image was developed hy using Modeler module of ERDAS Im- aging software. The data of features spectral reflective ratio was gained from field surveying. The spatial distribution infnrmation of fea- tures was gained with land use map and high resolution remote sensing image. The TM band 1-4 of Land Resources Satellite was select- ed as example. With the data, four band image of features spectral reflective ratio were simulated. The true color image and the stand- ard false color image were merged. Finally, the comparative analysis was given about the features spectral reflective ratio images simu- lated on different spatial information sources, and the future researching direction was pointed out.
