About the Maps

In the 19th century, ‘Sanborn’ maps were originally prepared for the exclusive use of fire insurance companies and underwriters. The Library of Congress has digitized many for public access. Many Chattanooga maps are now available. LINK

I aligned individual map pages to create a contiguous view, and as closely as possible, match to 2018 imagery.

Special thanks to the staff of the Hamilton County GIS Office for providing high resolution 2018 aerial imagery.
