Check out: The Secret Life of GeoTIFFs

In October 2022, the outcomes of a 2015 experiment to geo-reference 4,998 digitized maps of the Austro-Hungarian empire were shared with the public at the Computing Cultural Heritage in the Cloud Data Jam. Check out this recent post on World’s Revealed, the Library’s Geography and Maps blog, to learn more about the resulting GeoTIFF files enable access to digitized historical maps.

Georeferenced sheet 4962/Újpest (4962_002_geo.tif) from the Spezialkarte der Österreichisch-Ungarischen Monarchie map set depicts the northern end of Budapest and surrounding areas in 1917. This and other georeferenced sheets from the set are available online via the experimental Austro-Hungarian Map Set Data Package.
