Improvements in digital use and the further evolution of the map image are now also being implemented for additional scales following on from the 1:25,000 scale national maps. For the first time, swisstopo is now publishing the 1:50,000 scale maps in the new style.

Created from 1938 on, the 1:50,000 scale national maps replaced the time-honoured Dufour and Siegfried maps. Now this series of maps has also come to an end. The complete modernisation of the 1:50,000 scale national maps is starting in north-eastern Switzerland and will include all 78 sheets within the next few years.

The new 1:50,000 scale national map is largely and directly derived automatically from the topographical landscape model, which is an important geodatabase. When the automated processes reach their limits, the cartographers’ skills remain as essential as before. The new production processes also allow the 1:25,000 and 1:50,000 scale maps to be prepared in parallel, which helps to keep the maps up-to-date.

The map graphics have been discreetly upgraded and the colours used brought into line with those of the new 1:10,000 and 1:25,000 scale national maps.
