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.

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.

Cartographer

Guillaume Henri Dufour (September 15, 1787 - July 14, 1875) was a Swiss army officer, engineer and topographer. Though a career General and victorious military leader, he in 1864 presided over the First Geneva Convention, establishing the International Red Cross. As pertains to the cartographic world, was founder and president (1838 to 1865) of the Swiss Federal Office of Topography. The son of a watchmaker, Dufour had been sent school in Geneva where he studied medicine and drawing. He would go on to the École Polytechnique in Paris, then a military academy, where he studied descriptive geometry; this he followed studying military engineering at the École d'Application. When in 1810 he was sent to help defend Corfu against the British, he spent his downtime mapping the island's old fortifications. Later in his career he would be awarded the Croix de la Légion d'Honneur for his work repairing fortifications at Lyons. He returned to Switzerland in 1817, and to become commander of the Canton of Geneva's military engineers, as well becoming professor of mathematics at the University of Geneva. He continued to rise through the ranks and in 1831 was appointed quartermaster-general. In that capacity he was in 1833 commissioned to execute a trigonometrical survey of Switzerland. The final result of this monumental work, printed to 25 sheets on the scale of 1⁄100000, was published between 1842 and 1865. The Dufourspitze (the highest mountain peak in Switzerland) is named in honor of Dufour's cartographic achievements. More by this mapmaker...
