Digital Map Information
Geographicus maintains an archive of high-resolution rare map scans. We scan our maps at 300 DPI or higher, with newer images being 600 DPI, (either TIFF or JPEG, depending on when the scan was done) which is most cases in suitable for enlargement and printing.
Delivery
Once you purchase our digital scan service, you will receive a download link via email - usually within seconds. Digital orders are delivered as ZIP files, an industry standard file compression protocol that any computer should be able to unpack. Some of our files are very large, and can take some time to download. Most files are saved into your computer's 'Downloads' folder. All delivery is electronic. No physical product is shipped.
Credit and Scope of Use

How Large Can I Print?
In general, at 300 DPI, you should at least be able to double the size of the actual image, more so with our 600 DPI images. So, if the original was 10 x 12 inches, you can print at 20 x 24 inches, without quality loss. If your display requirements can accommodate some loss in image quality, you can make it even larger. That being said, no quality of scan will allow you to blow up at 10 x 12 inch map to wall size without significant quality loss. For more information, it is best consult a printer or reprographics specialist.
Refunds
If the high resolution image you ordered is unavailable, we will fully refund your purchase. Otherwise, digital images scans are a service, not a tangible product, and cannot be returned or refunded once the download link is used.
George Montague Wheeler (October 9, 1842 - May 3, 1905) was a surveyor and cartographer best known for leading the U.S. Government's geographical surveys west of the 100th meridian, better known as the Wheeler Survey. Born in Massachusetts, Wheeler attended West Point and graduated near the top of his class in 1866. He joined the Army Corps of Engineers and was dispatched to the American West, before being chosen to lead the ambitious survey that came to be associated with his name, which lasted from 1872 to 1879.

John James Stevenson (October 10, 1841 - August 10, 1924), better known as J.J. Stevenson, was a geologist and academic who played an important role in developing the field of geology in the United States. Stevenson was born in New York and attended New York University and then became a professor of chemistry at West Virginia University before returning to his alma mater to teach geology. Throughout the 1870s and early 1880s, he spent time with the still-evolving U.S. Geological Survey as well as the Pennsylvania Geological Survey. Later, in 1898, he served as president of the Geological Society of America. A prolific scholar, Stevenson published dozens of works over his long career. Learn More...
