The images for this collection were downloaded in 2007 from the Internet Archive, modified slightly, and saved in GIF format. The modifications were as follows:

  1. Straighten up the image (most were slightly tilted).
  2. Convert the image to GIF format.

The map formats and organization are changed from time to time. The processing required for downloads may be different in the future. The Internet Archive is not very well organized; finding a map usually requires the use of the archive's search engine.

The USGS topographic maps, the downloaded images, and the images in this collection are all in the public domain. You may use them for any legal purpose without permission or royalties. Although the maps are generally quite accurate, many of them are significantly out of date.
