The Austrian National Library (ÖNB) has received a remarkable donation of more than 46,000 digital aerial photographs covering all federal states of Austria from photographer Stefanie Grüssl. These stunning aerial images, captured between 2014 and 2019, are now publicly accessible through the library's digital platform, significantly expanding the institution's aerial photography collection to an impressive 51,000 photographs.

Visitors can easily search through the extensive photographic collection on ÖNB Digital using either federal state names or specific location searches. The comprehensive aerial photographs offer fascinating insights into Austria's natural landscape beauty and the country's ongoing infrastructure development over the five-year period. Grüssl created these remarkable aerial photographs through collaborative partnerships with Austria's Ministry of Interior and Ministry of Defense.

According to the Austrian National Library, aerial photographs serve as powerful tools for documenting and visualizing changes in our living environment that are influenced by climate conditions, weather patterns, and human activities. These images provide invaluable documentation of how Austria's landscape has evolved over time, capturing both natural and man-made transformations across the country's diverse regions.

In addition to Grüssl's contemporary donation, the National Library has released a groundbreaking new dataset titled "Austria from the Air," which contains metadata for approximately 4,800 historical aerial photographs from Austria along with the original images themselves. These historical photographs can be used, processed, and distributed freely without restrictions, making them accessible for unlimited public and academic use.

The black-and-white detail and panoramic shots of landscapes and cities date from 1930 to 1935, offering a unique window into Austria before the devastating destruction of World War II. These precious historical images show the country before urban sprawl, major road construction, and the development of commercial parks transformed the landscape. The Hofburg Palace alone is documented with nearly 600 photographs, providing an extraordinary visual record of this historic site.

Researchers can utilize this extensive photographic archive to analyze landscape changes over extended time periods and gather crucial data for climate research initiatives. The Austrian National Library emphasizes that these datasets enable scientists to visualize changes in cities and villages across decades, providing valuable comparative analysis opportunities for urban planning and environmental studies.

The comprehensive photographic data also supports the development of advanced machine-learning models that can automatically identify and categorize different types of landscapes visible in photographs. This technological application opens new possibilities for automated analysis of large-scale geographical and environmental changes. Additionally, the materials can be effectively utilized in aerial surveying and photogrammetry applications, supporting various technical and scientific research projects that require precise geographical documentation and measurement.
