1853 — Vector Covers of Historical Land Use — 2011 Edition (polygons)

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 mosaic of the various cartography was scanned at 1016 points per inch, georeferenced through the recognition of trigonometric points and known points, finally divided according to the cutting of the modern sheets 1:50,000 of the Istituto Geografico Militare. The legends of the various cards are quite similar and comparable to each other, agricultural activity is identified by very detailed conventional signs. The strong detail of these topographic maps allowed an interpretation of the conventional signs, in order to build a database of the use of “historical” land, with a legend built on three levels of the Corine Land Cover type, with a criterion of maximum possible similarity to that of the 2003 edition of the Land Use, in order to make the two products comparable. The 2011 edition also contains Valmarecchia, which has been part of the regional territory since 29 July 2009.
