Description

The City of Cambridge, Massachusetts, Geographic Information System (GIS) City-Wide 3D project provides a detailed three-dimensional model including the terrain, groundplan and buildings of the city. The city-wide model has been cut into one-kilometer squares for exchange with 3D design tools. Each file associated with the tiled 3D model is named with the prefix CAMB3D_ then the tile name, e.g. G5_, then the name of the dataset.

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 groundplan features and terrain

These tiled terrain layers were made with the following city-wide layers available for download from the City of Cambridge GIS. Except for the parcel boundaries, these data sets data were developed photogrammetrically by Infotec USA using aerial photography from April 2010.
