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.

Digital orders are delivered as ZIP files, an industry standard file compression protocol that any computer should be able to unpack.

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
Carl Wilhelm (Karel Vilém) Medau (1791 - February 16, 1866) was a prominent German lithographer, writer, and publisher. Born in Havelberg, Brandenburg in 1791, Medau was trained as a printer in Szczecin, which was then in Pomerania and is now the capital and largest city of the West Pomeranian Voivodeship in Poland. By the age of twenty-two, Medau was an experienced printer, and moved to Litoměřice, where he began working for the printer F. K Laube. Following Laube's death in 1817, Medau became co-owner of the firm by marrying Laube's widow, Elizabeth. The firm was renamed 'C.W. Medau' and Medau began modernizing and expanding the operation. In 1818, he became the first printer in Bohemia to submit an application to operate a 'stone-working workshop'(kamenotiskařské dílny), though the application was denied because there wasn't a police station in Litoměřice that could operate as a censor to oversee printing. Medau eventually obtained a printing license. In addition to this press, Medau also owned publishing houses and bookshops, and at least two newspapers, the 'Pražké Noviny' and 'Ceská Včela'. He tried to establish a branch of his firm in Prague in 1830, but was not successful. It would not be until 1843 that Medau would successfully create a place for himself in Prague. A unsuccessful revolution against the Austrian Empire took place in Prague in June 1848, in which Medau participated. One repercussion of the revolution was a tightening of censorship laws, which greatly effected newspapers and publishers. Medau would be forced to close the branch in Prague in 1855 as a result of this crackdown, which led to his business suffering financial difficulties. Medau died on February 16, 1866 and was buried in Litoměřice Cemetery. More by this mapmaker...
