Historic ADT Maps

Directions to open the files:
These maps are saved as GIFs, a format that saves files at 72dpi (dots per inch). Since most of these maps were scanned at 200 dpi, that means the GIF files will need to be resized to 36 percent of their original size to be viewed, or printed, at the size of the original printed map. (Maps 1997 through 2000 are at 150dpi, which means a 48 percent reduction.) The file size and approximate print size is listed below the date of each map.

To download files directly to your computer:
Netscape = Right-click on a map link, go to "Save Link As"
Explorer = Right-click on a map link, go to "Save Target As" Note: Explorer will not open large files, so saving the files to your computer and then opening them, is the only way to view the maps.

Please note directions above if you have trouble opening the maps below.
