Building on the rich geospatial data already provided, NYC DoITT is releasing a three-dimensional (3-D) Building Massing Model of New York City. The 3-D model includes every NYC building present in the 2014 aerial survey, the capture from which the model was developed. Using the Open Geospatial Consortium's specification as the basis, the NYC 3-D Building Massing Model was developed to a hybrid specification combining elements from Level of Detail (LOD) 1 and 2.

Highlights of the model include the differentiation of building components including roof, facades and ground plane. All major roof structures are modeled. Pitched roofs are modeled; however domes and rounded roofs are not. All roof appendages are excluded including but not limited to chimneys, parapets, spindles and antenna. In addition, a subset of 'iconic' NYC buildings was modeled to LOD 2.
Lastly the buildings are attributed with a Building Identification Number (BIN) to provide a means to associate other NYC data for analysis and rendering. For further details, see the included metadata. The 3-D model was a one-time capture. If the model proves useful, future updates and extension will be considered.
