Documentation of the Glacier Retreat in the Eastern Part of the Granatspitz Mountains (Austrian Alps) Using Aerial Photographs for the Time Period 2003-2009

Abstract: This paper documents ongoing glacier retreat in the eastern part of the Granatspitz Mountains (Hohe Tauern Range, Austrian Alps) for the time period 2003–2009 using aerial photogrammetry. Aerial photographs of 2003, 2006, and 2009 were made available by the Hydrological Service of the Regional Government of Salzburg, the Federal Office of Metrology, Surveying and Mapping, Vienna, and the Regional Government of the Tyrol, respectively. High resolution multi-temporal digital elevation models and digital orthophotos of the area of interest were derived using digital photogrammetric methods to provide a sound basis for glaciological research. Glacier outlines of the three glacial stages were mapped interactively. Temporal change in area and surface height of the glaciers mapped clearly document glacier retreat. Glacier mass balance based on the geodetic method was calculated for Stubacher Sonnblickkees (Glacier). Mean annual specific net balance amounts to −656 mm w.e. for the time period 2003–2009, w...

Digital Camera Nikon D300 in Support of High Mountain Studies in the Langtang Valley, Central Himalaya, Nepal

Abstract: This paper describes two different mapping projects in the upper Langtang Valley, Central Himalaya, Nepal, applying close-range photogrammetry using a non-metric consumer-grade digital camera Nikon D300. Data acquisition (terrestrial photographs, and additional handheld GPS and laser distance measurements) was carried out during a field campaign in April 2010. The first mapping project aimed to document the present extent of the glacier tongue of Kyimoshung Glacier, Langtang Himal, and to compare this glacial stage with an earlier one (1992). The second mapping project intended to produce a large-scale map of Kyanjin Gompa for socio-economic studies. Kyanjin Gompa is a small settlement with a fast growing tourism infrastructure. Photogrammetric work was supported by commercial software, such as ImageStation of Intergraph and/or PhotoModeler. The results obtained are presented graphically using maps and numerically.
