The Infrared Space Observatory ISO, launched by ESA in November 1995, ended its operations succesfully in April 1998. The subsequent post-operational phase, which will last for 3,5 years, is devoted mainly to re-analysis andre-calibration of the data. The ISOPHOT Interactive Analysis (PIA) is not only the main calibration tool but also the software tool of choice for the scientific analysis of data obtained with the imaging spectro-photo-polarimeter ISOPHOT. Some of the main PIA enhancements related to mapping are presented in this paper: the development of new algorithms for the obtention of ISOPHOT maps as well as a sub-package for beam profile deconvolution.
