Amassed at the suggestion of Emmanuel de Martonne, the collection of glass plates is composed of 11 080 snaps taken on the greater part by geographers of the University of Paris between 1898 and 1954. It covers the whole world and is sorted out by continents, countries, regions and sub-regions, according to administrative boundaries used at a certain time. It is approximately made out of : 2 056 plates on France, 3 016 on the rest of Europe, 2 249 on Africa, 1 981 on the Americas, 1 242 on Asia, 285 on the USSR, 98 on Australia, 30 on the Arctic ,36 on Antarctica and 16 on Oceania. E. de Martonne, Ch. de Robequain and J. Dresch are the most represented authors.

      For some plates, the accompanying text of the shooting on the label of the original plate is finely handwritten and presents a detailed description of the site ; in this case, a search for the precise geo-localization has been undertaken. But sometimes, the key gives little information and presents only a name, without any other indication ; in that case, the geo-localization centers on the country, even on its capital city. Besides, the date of the photography is rarely mentioned, it thus corresponds to the period between 1898 and 1954, but the computing constraints do not allow to note two dates ; that is why so many glass plates match the year 1898.
