SUMMARY
The contribution highlights the need for the connection between urban transformation assessment and real estate assessment, noting that there is a mutual influence (now rarely seen) between the parameters involved. For this purpose GIS serves as a tool by which to achieve this liaison. The list of applications for real estate conducted through the use of GIS, its strengths and weaknesses and fields in which applications are still pioneers, argues in favor of the hypothesis outlined and give to the assessor a key role in its implementation.
