We propose and explore the potential of a method to extract highsignal-to-noise (S/N) integrated spectra related to physical and/ormorphological regions on a 2-dimensional field using Integral FieldSpectroscopy (IFS) observations by employing an optimization procedure based oneither continuum (stellar) or line (nebular) emission features. Theoptimization method is applied to a set of IFS VLT-VIMOS observations of(U)LIRG galaxies, describing the advantages of the optimization by comparingthe results with a fixed-aperture, single spectrum case, and by implementingsome statistical tests. We demonstrate that the S/N of the IFS optimizedintegrated spectra is significantly enhanced when compared with the singleaperture unprocessed case. We provide an iterative user-friendly and versatileIDL algorithm that allows the user to spatially integrate spectra followingmore standard procedures. This is made available to the community as part ofthe PINGSoft IFS software package.
