Regional historical map - Historical land use - 2011 edition

This new version of the historical land use database also contains the seven new municipalities of Valmarecchia. At the end of the 90s a collaboration between the Institute for Artistic, Cultural and Natural Heritage and the Geographic Information Systems Service of the Emilia-Romagna Region allowed the construction of a historical-regional cartography derived from the pre-unification productions from 1828 to 1853. The the regional territory is covered by the Austrian Topographic Map (scale 1:86.400) and, for a small portion, by the Topographic Map of the mainland States of His Majesty the King of Sardinia of 1853 (scale 1:50.000). The so-called Austrian Topographic Map actually consists of various cartographies made several times, according to the natural and progressive commitment of the Military Engineers of the Imperial Royal Austrian Army to map the Italian territories subject to the government of Vienna or controlled by it. The mosaic of the various cartographies was scanned at 1016 dots per inch, georeferenced through the recognition of trigonometric points and known points, finally subdivided according to the cut of the modern 1:50,000 sheets of the Military Geographical Institute. The legends of the various cards are quite similar and comparable to each other. The strong detail of these topographic maps allowed an interpretation of the conventional signs, in order to build a database of "historical" land use, with a legend built on three levels of the Corine Land Cover type. This legend has been elaborated with a criterion of maximum possible resemblance to that of the other regional editions of land use, to make the products comparable with each other and to allow reconstructions of the changes in the government of the territory over a span of 150 years.
