The information assists homeowners directly in their ownership responsibilities by providing the current value and tax status of their property. Professional real estate, business and legal entities access and draw upon Boston property parcel data to support and enhance their specific business operations. The GIS data appended to this application provides valuable graphical contexts for researchers, analysts and other professionals interested in demographical patterns, property usage and development.
