--- Start of Idrisi List message Hello Everyone, PCA has often been mentioned as a sound statistical technique for vegetation monitoring (Refer IDRISI guides). Second component thus obtained is said to capture the required information in this context. After running PCA on the images of two dates, what is the recommended technique for cahnge detection, e.g. simple overlay? I found Oliver Tomlinson's response in the mail archives : "I often use components to classify an image rather than raw input image bands." But could not find his email address. Does he mean simple reclassification or something else? Please excuse my ignorance. Any help / suggestions would be greatly appreciated. Regards.
