Habsburg topographic cartography of the Italian peninsula in the first half of the 19th century
The geodetic point lists of the Habsburg survey of the Italian peninsula, carried out in several steps after the Napoleonic wars, were digitized and analyzed together with the modern coordinates of the identified points. Assuming the usage of the Zach-Oriani hybrid ellipsoid, the Burša-Wolf type datum transformation parameters were estimated between the local, historical triangulation Datums and the WGS84.
