WebThe Tasseled Cap Transformation is a technique commonly used in land cover mapping or other classification projects. It takes the linear combination of satellite imagery bands and a specialized coefficient matrix to create a n-band image with the first 3 bands containing the majority of the useful information, similar to Principal Component Analysis. WebApr 13, 2024 · In addition, indices used as proxies need to be viewed critically, regardless of whether they are multi-dimensional indices such as the Tasseled Cap components or uni-dimensional indices. The “lack of confidence” is attributable to the difficult understanding and interpretation of them. WebA Tasseled Cap Transformation is performed by taking “linear combinations” of the original image bands, which is similar in concept to the multivariate data analysis technique called principal components analysis (PCA) .
