Wetland types of Yellow River Delta are various and serious phenomena of 'same object with different spectrum' and 'different object with same spectrum' is one of the reasons caused low classification accuracy. Combination with multi source images is an efficient method to mitigate this influence. In the paper, principal component transform was carried out to Radarsat four polarization data and the...
High spectral resolution, high spatial resolution and high temporal resolution are the development trend of modern remote sensing technology. In the case of same image data, it is difficult to obtain high spatial resolution and hyperspectral remote sensing data information simultaneously. This weakness can be remedied, the quality of the image can be improved and the useful thematic information also...
Multi-spectral image keeps good multi-spectral feature in spite of its low special resolution, which canpsilat describe the earthpsilas surface information in detail. In contrast, panchromatic image keeps high special resolution but with limitations in spectral feature. The advantages of both multi-spectral image and panchromatic image can be integrated in the same image with fusion technique, so...
