Digital Map Information

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
Jean-Baptiste Poirson (March 6, 1761 – February 12, 1831) was a French engineer, globe-maker, geographer, and cartographer active in the late 18th and early 19th centuries. Poirson was born in Vrécourt (Vosages), France, the son of the town's master blacksmith, Pierre Poirson. Completing his studies in mathematics, Poirson took a position with the map publisher Edme Mentelle (1730 - 1815). From about 1790, maps begin appearing under the Poirson imprint. Having attained some recognition for correcting the work of earlier geographers, Porison was part of a team that collaborated on a large terrestrial globe for the instruction of the Dauphin. After 1803, he was again called on to produce an updated globe, this time for Napoleon Boneparte (this globe is preserved at Fontainebleau). Among his more significant works are the maps associated with the French edition of Alexander von Humboldt's Atlas Geographique Et Physique Du Royaume De La Nouvelle-Espagne. He also worked with Conrad Malte-Brun (1775 - 1826) and François-Raymond-Joseph de Pons (1751 - 1812). In 1825, Poirson and his wife settled in Valence-en-Brie (Seine-et-Marn), purchasing a house on the main street, today's Rue André-Taboulet. He died there in1831 and was survived by his son, the famous French playwright Charles-Gaspard Delestre-Poirson (1790 – 1859). More by this mapmaker...
