A new work field presented itself in 1863 as the newly established Swiss Alpine Club decided to issue yearbooks including maps. Many of these tour maps were engraved by Leuzinger and hence almost all volumes contained work by his hand. Because the tour maps were often based on the original geodesic recording by the Federal Topographical Bureau (Eidgenössisches Topographisches Bureau), Leuzinger developed a close relationship with this organisation, in particular with Colonel Hermann Siegfried. When in 1868 the Federal Parliament (Bundesversammlung) decided to issue a new Topographic Atlas of Switzerland, Siegfried commissioned Leuzinger to do the difficult engravings of the mountains - based on the original maps of Dufour and Siegfried himself. Leuzinger then made no less than 117 monochrome engravings for which he was lauded both in Switzerland and abroad. He also made many other maps, partly in copper engraving, partly in chromolithography, highlights being some maps of Switzerland, maps of the Canton of Neuchâtel Canton of Bern and Canton of Aargau, special maps of Central Switzerland, Bernese Oberland, Grindelwald area and the mountain Rigi as well as a large map of France.
