Rétro-observation des processus de décrue glaciaire à partir de peintures. Apports de la mono-photogrammétrie

Abstract : Alpine landscapes are indicators of climatic variations recognized through their geomorphological and glacial dynamics. In this field, the old documents (photographs, engravings, paintings…) constitute important data sources, used for the purposes of retro-observations. The classical methods consist, most often, to exploit them in descriptive works then being the subject of naturalistic cartographic retranscriptions. Today the contribution of innovative methods of treatment, such as mono-photogrammetry, offer new perspectives. It is thus possible to extract quantitative information from qualitative archives. This approach allows, in addition to a conventional landscape analysis, to project the information contained in the images for the spatial analysis. In the current context of climate change, a new mapping of the evolution of the ice extent is a result that completes the current modeling work. The Mont-Blanc massif offers a field of study adapted to several titles. Historically, the origins of mountaineering and glaciology lie in this massif and provide a large number of archives since the early nineteenth century. Today, due to climate change, several glaciers are regularly monitored, with high spatio-temporal precision. This context therefore favors exploratory and comparative work to test the use of these new methods.
