Regional Historical Map - 1:50.000 - printable version with cartouche

Cartographic series taken from the Austrian (scale 1:86,400) and Piedmontese (scale 1:50,000) topographical production of the first half of the 19th century. It is a primary knowledge base in terms of completeness of content for an interpretation of the pre-unification Italian territory. of this editorial initiative, from this historical documentation available for almost all of northern and central Italy, the data relating to the area of ​​the Emilia-Romagna. The photographic images of the original sheets were scanned at 1016 dpi (dots per inch), recognized about 15 trigonometric points for each sheet, affine transformations of the images constrained on the analytical coordinates of the known points were performed; the new georeferencing presented metric residuals with very low values; this also confirms the excellent quality of the historic papers.

lineage The photographic images of the original sheets were scanned at 1016 dpi (dots per inch), recognized about 15 trigonometric points for each sheet, affine transformations of the images constrained on the analytical coordinates of the known points were performed; the new georeferencing presented metric residuals with very low values; this also confirms the excellent quality of the historic papers. From the files thus created, the base described here was finally obtained by reducing the resolution to 200bpi.
