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
You can use your digial image any way you want! Our digital images are unrestricted by copyright and can be used, modified, and published freely. The textual description that accompanies the original antique map is not included in the sale of digital images and remains protected by copyright.

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.
The United States Geological Survey (1878 - Present), aka the U.S.G.S., is a scientific agency of the United States government, which was founded in 1879. USGS scientists study the landscape of the United States, its natural resources, and the natural hazards that threaten it. The organization has four major science disciplines: biology, geography, geology, and hydrology. It is a bureau of the United States Department of the Interior and is the department's only scientific agency. More by this mapmaker...
Bailey Willis (March 31, 1857 - February 19, 1949) was an American geological engineer and university lecturer. Later in life, he became one of the world's leading experts on earthquakes. Born in Idle Wild-on-Hudson, he was taken to Germany and England at the age of thirteen for four years of schooling. During this time, he gained fluency in German, allowing him to read many scientific texts that were only available in that language. He then enrolled in Columbia University and earned degrees in mechanical and civil engineering in five years. After graduating from Columbia, Willis worked for Northern Pacific Railroad as a survey geologist from 1881 until 1884, when he moved to the U.S. Geological Survey. He worked for the USGS until 1915 and was named director of the Appalachian division in 1889. Willis lectured in geology at Johns Hopkins University from 1895 until 1902 and was appointed head of the Division of Areal Geology for the USGS in 1900. He led an expedition to China for the Carnegie Institution in 1903 and wrote a book entitled Friendly China about that experience. He then consulted for the government of Argentina from 1910 until 1914 and wrote another book, entitled A Yanqui in Patagonia. In the 1920s, he launched an intense campaign to increase knowledge of earthquake hazards and safe building practices. After leaving the USGS in 1915, Stanford University appointed Willis a professor and chairman of their geology department, a position he held until 1922. He was elected to the National Academy of Sciences in 1920 and served as president of the Seismological Society of America from 1921 until 1926. Willis was also influential in getting Mount Rainier designated as a national park. In 1882, Willis married his cousin, Altona Grinnell, with whom he had two children, one of whom died in infancy. Altona died in 1896. He then married Margaret Baker in 1898, with whom he had three children. Margaret died in 1941. Learn More...
