Multi-temporal photographic dataset of glacier changes in the Rupal Valley, Nanga Parbat, north-western Himalaya

The elevation of viewpoints of re-photographic surveys ranges between 2940 and 5370 m a.s.l. The research is based on the hypothesis that repeat photography of these mountain glaciers allows for a longer monitoring period than remote sensing data as historical metric photographs from the years 1934, 1958, and 1987 are available.

All relevant historical photographs showing glacier aspects taken during scientific expeditions have been collected from archives and repeated from the same viewpoints during several surveys between 1992 and 2010. Prints of the selected photographs were taken to the field in order to identify the exact viewpoints. The camera was always mounted on a tripod for careful selection of the view angle and frame.
