Description
The City of Cambridge Geographic Information System (GIS) City-Wide 3D project provides a detailed three-dimensional model of buildings and bridges has been compiled from many sources over several years. The FBX building model collection provides 3D models for modeling, model transformation, and web visualization. The model collection is segmented into tiles which is contiguous with the City of Boston 3D tile grid. Each model being assigned to the tile that its centroid falls within.
The Tiled CAD datasets provides exports of several layers from the Cambridge GIS Data Dictionary.
Purpose
These tiles are made available for users who want to use design tools to re-mix basemaps or to develop schemes involving altered ground plan features and terrain

Sources
These tiled ground plan layers were made with the following city-wide layers available for download from the City of Cambridge GIS. These data sets data were developed photogrammetrically by WSP using aerial photography from various flyovers from 2012 to 2023.
Coordinate System
Tile Scheme and Coordinate System:
The 5000 foot tile scheme is designed to facilitate exchange of precise georeferenced models and context information among a variety of authoring and presentation tools. The tile network covers the greater Boston area.
State Plane coordinates are offset to keep all coordinates within limits inherent in most 3D design tools.
Projected Coordinate System:
State Plane Massachusetts Mainland (Feet), North American Datum of 1983.
