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.
Youzheng zongju (郵政總局; 1896 - 1949), known in English as the Inspectorate General of Posts or Imperial Chinese Post under the Qing Dynasty and the Directorate General of Posts, Chunghwa Post, or simply the Chinese Post Office after 1911, was the primary postal service operating in China during the years of its existence. It was created in the wake of the First Sino-Japanese War, a series of reforms meant to account for China's weakness vis-à-vis its much smaller but more modernized neighbor. After the Qing collapsed and China entered a period of political fragmentation, the postal service was an important basis for building national identity and the hopes of national reunification. Like the Maritime Customs Service, of which it was originally a branch, the postal service was nominally a part of the Chinese state (under the Ministry of Communication) but was independently managed and staffed with many foreigners, especially at the senior level. This insulated it somewhat from the incessant political and military struggles of the Republican Era (1912 – 1949) and allowed it to operate across jurisdictions, even in some Japanese-occupied areas during the Second World War (Second Sino-Japanese War). At the same time, it came under increasing control from the late 1920s onwards, as the government of Chiang Kai-Shek aimed to centralize power and enforce censorship, a harbinger of its future after the Communist takeover in 1949 (when China Post was formed, retaining the name Youzheng zongju in Chinese until it was partially separated from the government and established as a state-owned enterprise in the 1990s and early 2000s).
