The GISMO meeting held at the Fund for the City of New York featured a presentation by Amanda Cruz, who directs the Tax Map Unit and other GIS initiatives for the NYC Department of Finance. Amanda discussed Finance’s 3D GIS capabilities which allows improved visualization of tax lots. She covered the process of moving from 2D to 3D mapping, detailed the technologies utilized, and described cloud infrastructure integration. Amanda also provided an overview of Finance’s use of Cyclomedia data (https://www.cyclomedia.com/us) and how it is being integrated into Finance Department assessment operations with resulting increases in productivity and in City tax revenues. Amanda’s presentation will have important implications for other City agencies.
