Aerial photographs

The aerial photographs of Cape Cod, a New England town center, a suburban neighborhood, Brooklyn, Oahu and a desert city grid are U.S. Geological Survey imagery from The National Map, which is in the public domain. Each one is cropped, toned, and on some pages redrawn as dots.

Maps

The map of every U.S. county comes from the us-atlas project, built from the Census Bureau’s cartographic boundary files, which are in the public domain. The Massachusetts towns are placed by their published coordinates and sized by the Department of Revenue’s count of single-family homes.
