1853 — Vector covers of historical land use — 2011 edition (points)

The regional territory is covered by the Austrian Topographic Charter (scale 1:86,400) and, for a small portion, by the Topographic Charter of the Land States of His Majesty the King of Sardinia in 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 Military Geographic Institute. The legends of the various cards are quite similar and comparable to each other, the agricultural activity is identified through 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 “historic” land use, with a legend built on three levels of 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 the Valmarecchia, which since 29 July 2009 has been part of the regional territory.
