The Second Military Survey

The First Military Survey (1763-1785) May 21, 2014

We are continueing the online publication of the military surveys of the Austrian Empire. The map sheets of the first military survey (1763-1785) about Lower and Upper Austria are now available!

The scale of the first military survey’s sheets was 1:28 800. The sheets did not base on accurate measurements, they were compiled from old maps and by à la vue mapping, that is the reason the accuracy of the first survey can’t approach the accuracy of the latter ones. This also means that it was impossible to georeference the sheets precisely, and the accuracy of the goereferencing sometime higher than 300 meters.

Along with this we are happy to announce that the maps are now available online!
