ABSTRACT
As mentioned in Section 1.1, this book has an environmental scope, and it is intended to improve the readers’ understanding of how remote sensing (RS) techniques are used to extract relevant information from the Earth system. Therefore, we will place more emphasis on the interpretation of the images rather than on the acquisition process, which has been reviewed in previous chapters. Before addressing visual or digital interpretation methods, this chapter reviews a series of introductory concepts that may help the reader to better manage a project dealing with RS data.
