Prussian General Staff Card 1 : 86 400 half degree division 1816 - 1847 (HKPG)

Prussian General Staff Card 1 : 86 400 half degree division 1816 - 1847 (HKPG) The 85-page map work of the Prussian General Staff was based on the map works of the neighbouring states in the older French scale 1 : 86 400. The basis for the reproduction was the tranchot/of Müffling's maps of the Rhineland and supplementary measurements in the adjacent areas. Geographical grid lines at a distance of half a degree of longitude and a quarter of a degree of latitude limit the maps, which are approximately 41 cm x 32 cm in size. They correspond to 3 x 2.5 sheets of today's digital topographic map 1:25000. The additional designation ‘half-degree division’ is derived from this, since 4 sheets (sections) each form a half-degree division of 1° x 30’. The reproduction of the cards was done monochrome by stone printing. They were not published because of the exclusively military purpose. A handwritten 'Statistical Tableau...' from 1837 provides information on size and population, agricultural yields, trade and industry. It is available as a monochrome print (81 cm x 54 cm).
