State photo of the Duchy of Schleswig by H. du Plat, Historical map

The topographical photographs, mainly from the last quarter of the 18th century, were recorded in 1804 and 1805 by H. du Plat, Pr. Lieutenant in Cron Printzen Regiment, with the help of Lieutenants Ferd. Bauditz, Fr. Wilster and Tauencia collected and recorded. The original scale is 1:57,600. The cards were reissued in a scale of 1:100,000 in 8 partial cards. The 8 cards are additionally available in a folder with a cover sheet and explanations in German and Danish. The historical maps are contemporary cultural witnesses of cartography and in particular reflect the political distribution of power. The historically interested user of the map can easily get a picture of the prevailing power of the country and the subsequent developments. The map representation is unusual compared to today’s cards. This mainly includes compliance with an odd scale. The reason is the conversion of rod, cubit or foot dimensions. Furthermore, the maps mainly served the military purposes of the respective country master!
