IKONOS数据在土地利用动态监测中的应用方法研究





对高分辨率(1m)的多光谱IKONOS影像在土地利用变化动态 监测中的应用方法进行了研究试验.通过对结果的分析和与其他常规方法结果的对比分析,提出了将多光谱IKONOS影像和全色SPOT影像叠加作主分量变 换,然后选取适宜的特征分量进行假彩色合成的方法,来生成光谱特征变异影像以突出变化信息.该组合方法不仅能保持原有影像的丰富信息,而且可突出变化信 息,充分展示了IKONOS影像的巨大应用潜力.

-Study on IKONOS data in Land Use Dynamic Monitoring Method for high-resolution (1m) multi-spectral IKONOS Images in Land Use Change Dynamic Monitoring test methods were studied by analysis of the results and with the results of other conventional methods comparative analysis, the multispectral IKONOS image and panchromatic SPOT image superimposed primary component conversion, and then　the appropriate feature component of false color composite methods to generate images to highlight the variation in spectral characteristics change information. this combination not only You can maintain the original image of the wealth of information, but also to highlight changes and information, demonstrating the enormous potential IKONOS images.
