The Normalized Difference Vegetation Index (NDVI) and the Tasseled Cap Transformation (TCT) method are generally used for low-resolution satellite images of vegetation explicit methods, and this study was to develop the suitable high resolu- tion satellite images of vegetation display technology based on the above-mentioned methods. The experimental results show this technology can significantly increased the accuracy and definition of extracted vegetation, which can effectively support the follow-up interpretation and mapping operations.
