Basemap PDF

GIS File Name





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 PDF Basemap is a vector-based basemap that has layers that can be selectively turned on and off using Adobe Acrobat to create custom basemaps. These files can also be edited in Adobe Illustrator or Photoshop to apply custom styling or to edit features.

Usage Notes

  • To control the individual layers in this PDF, open in Acrobat Reader or Acrobat Pro, and open the Layers panel.
  • To create a custom basemap for a tile open the PDF in an editing tool, and save as a high-resolution image. Make sure that the extents of the image are the exact same extents of to original PDF. Then you can apply this new basemap as a texture in SketchUp.
