Description
The City of Cambridge, Massachusetts, Geographic Information System (GIS)
City-Wide 3D project provides a detailed three-dimensional model including the terrain, ground plan 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 2010 Basemap layer provides a clear reference map showing the edge of paved and planted areas as well as labeled 1-foot contours, street names, pavement markings and parcel boundaries. In all, 24 layers from the Cambridge GIS were graphically ordered and styled and then clipped to each tile boundary. The original layers were developed from stereo photogrammetric methods, with a precision of about six inches. The cell size of the basemap layer is approximately 12 centimeters.
Purpose
This basemap is useful as a visual reference for the ground conditions as it relates to terrain and buildings. It can be used as a setting and a initial condition for detailed design studies.

Sources
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.
Coordinate System
Universal Transverse Mercator Projection, Zone 19, WGS84.
Usage Notes
These images have extents that align precisely with the tile boundary included with all of the other data Camb3D files for easy registration. In SketchUp, ground plan images may be easily applied the terrain. From the Materials Window, use the eye dropper to select the terrain material, then choose the desired ground plan image in the Edit tab.
