The emergence of a new generation of instrumentation in astrophysics, which provide spatially-resolved spectra over a large 2-dimensional (2D) field of view, is opening up a new frontier in the development of surveys based on samples of hundreds of spectra in a 2D context. The observational techniques introduced in this book represent the first attempt to obtain continuous coverage spectra of the disk of a galaxy in the nearby Universe, by the application of the Integral Field Spectroscopy (IFS) technique. A self-consistent methodology is defined in terms of observation, data reduction and analysis techniques for wide-field IFS surveys. This novel approach is used to analyse the properties of the ionized gas and to perform a detailed 2D study of the emission line spectra in a sample of nearby spiral galaxies. This work should be particularly useful to astronomy graduate students and advance researches with interests in the study of the interstellar medium, chemical abundances in...
