The term special card is the opposite of the general map and is used in two ways in the German-speaking world:
- on the one hand for some detailed thematic maps that are dedicated to a special topic - for example a geological map enriched with tectonic details , or a distribution map for a rare plant species
- on the other hand for earlier, very large-scale topographical maps , where special emphasis is placed on the fine representation of the terrain .
A map series of the second type was the special map 1: 75,000 of Austria-Hungary , the publication of which the military topography began at the end of the 19th century and completed by around 1910. It was still drawn in the style of a hatched map, but with a particularly precise representation of the fall lines of the terrain. Due to its high accuracy and area-wide availability, it could - enlarged to a scale of 1: 50,000 - serve the successor state Austria as a provisional map of 1: 50,000 when the economic emergency did not allow the more modern ÖK 50 to be completed quickly .
A map series 1: 144,000 of military geography was temporarily designated as a special map in Austria (around 1890) , which formed the basis of the later general map 1: 200,000.
