[ES]La transformación de componentes principales se utiliza para realzar zonas que han sufrido cambios normalmente asociados a variaciones en la cobertura vegetal, que, según numerosos autores, se hacen particulamente visibles en los componentes de orden elevado. Dichos componentes son posteriormente clasificados por técnicas no supervisadas en grandes clases dinámicas, comparándose los resultados con otras clasificaciones realizadas a partir de cada una de las imágenes estudiadas, como se ha venido haciendo clásicamente.
[EN]The principal components transformation in used to highlight areas that show a change in time, normally associated with fire damage and vegetation regrowth. These variations are enhanced in the high order components, following previous studies. The components are classified by unsupervised techniques to yield thematic maps on which dynamic cover type classes are recorded. This maps are compared with others based on the individual images, normally used in classical methods.
