UPDATE 3/26/09 – After a long hiatus, I’ve finally started working on a major update to this project and will be recompiling the entire collection as well as adding at least 1,000 more maps. This is turning into a huge project and would be great to get some help. If you want to volunteer to help out there are several things you can do to contribute:
- I’m looking for server space. Could probably use 40 or 50 gigabytes.
- If you’re a map librarian that’s looking at putting scans of historic topos online, let me know. I can easily convert them to Google Earth and add them to the collection.
- If you have access to historic topographic maps, but no way to scan them, let me know. I may be able to find someone with access to a large format scanner that might be willing to help out.
- If you know how to georeference maps, I have several 1,000 maps that need to be georeferenced before they can be imported into Google Earth.
- If you have Photoshop, I have something you can do.
If you want to contribute, please contact me
Currently, this collection has over 2,000 historic USGS Topographic maps covering several areas of the United States. The maps are available in various scales and date back as early as the 1800s in many areas.
Instructions:
Just click on one of the indexes, find the area you are interested in, click on the placemark in the center of the outlined area, then click on blue hyper link for the map year you want to view. The maps will appear under Temporary Places. You can delete them from there when you’re done.
Original Data From:
I have converted the maps for Google Earth, but I did not scan any of these maps. They were obtained them from many different sources including:
- University of Nevada Reno Mary B Ansari Map Library
- California State University, Chico Meriam Library
- University of California Berkeley Earth Sciences & Map Library and here and here.
- USGS Bay Area Regional Database
- University of California Santa Barbaray Alexandria Digital Library
- Fort Lewis College Center of Southwest Studies
- University of New Hampshire Government Information Department
- Maptech.com
- North Carolina State University GIS Data Services
- University of Washington – Early Washington Maps
- NOAA Historical Map & Chart Project
- New Jersey Geological Survey
- USGS Gulf Coast Historic Topographic Maps
- Pennsylvania Spacial Data Access
- Delaware Geological Survey
- SDAG Historic Topographic Maps of San Diego County
- Historic Topographic Maps 1:250,000, University of Texas Austin.
- University of Hawaii Manoa Library
I would like to thank the above sources for making their collections available to the public for download. Historic topographic maps are a valuable public resource and it’s good to see libraries acting in the best interest of the public by making the maps available to the public.
Please let me know if you know of any other online historic topographic map resources and I will add it to the list.
Below are several more great online historic topographic map collections. Unfortunately, the curators of these collections do not make the full maps available for download and, in some cases, attempt to claim copyright protection (even though I’m pretty sure scanned USGS topographic maps are exempt from copyright protection). Hopefully the curators of these collections will someday come to their senses and make their full scans available to the public domain. These maps are a national treasure and belong to the public.
