The digital collection Maps of the Ottoman Empire has been created by the Digital Library for International Research. The collection contains 19 maps held by the W. F. Albright Institute of Archaeological Research (AIAR) in Jerusalem. The maps were created between 1839 and 1906, brought together in 1915 by the British Intelligence Division War Office, and published by the British War Office. The maps show mainly the eastern and southern part of the Ottoman empire, now Iraq and Syria, and there are maps for Lebanon and Jordany.
The online finding aid and virtual collection Bildsammlung Palästina has been created by the Bayerisches Hauptstaatsarchiv in Munich. This collection contains some 2,100 aerial photographs and 400 other photographs – the last mainly made in Palestine, but also in Syria, Iraq, Turkey and Serbia – taken in 1917 and 1918 by the Bayerische Fliegerabteilung 304, a unit of the Bavarian Army for aerial reconnaissance.
The digitized images have been divided in five main sections: images of the coastal area; the mountains from Lebanon to the Hebron; the valley of the Jordan; Eastern Jordany, and other photographs taken on the ground. The photographs show information about the fronts in the Middle East, but they are also important for the archaeology of the region. The collection can be searched with a free text search field, and you can browse the five sections. The website is accessible in German. In the last section you will find also images of the Bavarian pilots and their unit.
A recent article by Wilhelm Füßl, ‘Luftbildfotografie im Ersten Weltkrieg’ at Visual History gives you more information about German aerial photographs from the First World War.
