General Session Description
By leveraging GIS, New York City developed a state-of-the-art three-dimensional tax map and a one-stop shop portal for property owners. Property owners can verify their building and land data for accuracy, view and challenge their assessments and exemptions, view their sales, mortgages and recordings, and trace the history of lot changes to their parcel. The three-dimensional perspective lets assessors walk around buildings and see interior floor plans. The 3D feature enables the potential development of 3D variables, such as views, for valuation. The 3D visualization is particularly important for air lots as it shows the potential for development. We will discuss the challenges in building a 3D cadastre, such as data collection, public and city leadership support, and integration with other city agencies, along with advances in technology that made it all possible.
