The Adige River map in 1:20,736 scale by Leopoldo de Claricini-Dornpacher (1847)

In the 50th year anniversary of the November 1966 Adige river flood, which hit at the same time Florence and Venice 14 map sheets of the Adige river valley between Meran and Borghetto, in northern Italy, were scanned in high-quality and printed for the public ac-cess and use. The lithograph was printed in 1847 in a 1:20.736 scale (1”:288° i.e. 1 Zoll=288 Klafter) in Innsbruck by Leopoldo de Claricini-Dornpacher (1812-1888) and depicts the river and its valley as it was in almost natural conditions when the river training works just started in the intermediate reach. A georeferencing of one sample sheet shows that a RMSE between 10 and 15 meters can be reached. A comparison with the actual geomorphology of the river especially in its southern reach is possible thanks to the map. One of the objectives of this study is, also, to make a beautiful map accessible to a wide public, to let people enjoying the river landscape as it was and will never return, until the next glacial era.
