The recent introduction of the IMU (Municipal Property Tax) in Italy has highlighted the vexed question of inequality existing in cadastral appraisal systems. This article outlines the methods and activities, in the field of mapping, supporting of the important process of renewal of the entire cadastral system. It describes the technology and spatial data currently available that can assist in setting up complex issues of reforming appraisal system and, more generally, in the processes against tax evasion in real estate. This paper aims to offer a contribution to the documentation and comprehension of geo-referenced data of the real estate in Italy and processing and analysis tools. The contribution is related to both the hypothesis of a reform of the cadastral appraisal system and, more generally, to the fight against tax evasion in real estate, and to the regular institutional Agency’s (Agenzia del Territorio – AdT) activities recently incorporated in the “Agenzia delle Entrate”. We will discuss AdT data and the technologies of the Agency; then the data and technologies outside the domain of the Agency, but closely related to and interoperable with the first one.
