Application of archival aerial photogrammetry to quantify climate forcing of alpine landscapes

“…Geomorphological research is always in need of three‐dimensional data to describe topographic surfaces and to monitor their change over time. The possibility of generating quantitative elevation data from stereo photography has played an important role in this regard, as demonstrated by pioneer applications of photogrammetry to geomorphological studies (Wickens and Barton, ; Welch and Jordan, ; Small et al., ; Chandler and Cooper, ; Chandler and Moore, ; Lane et al., ). With the advent of fully automated methods and the transition from traditional to digital photogrammetry during the 1990s, photogrammetry became a widely used, cost‐ and time‐effective approach for geoscience research (Lane et al., ).…”

Impact of glacial erosion on 10Be concentrations in fluvial sediments of the Marsyandi catchment, central Nepal

“…In contrast, several studies have investigated the sediment budget of glacier‐fed streams or basins to derive large‐scale estimates of glacial erosion. These reconstructions, however, require very good preservation of sediment records, which is not common in many contexts [ Small et al , 1984; Riihimaki et al , 2005; Staiger et al , 2006; Koppes and Hallet , 2006; Dowdeswell et al , 2010].…”

Application of Digital Photogrammetry to Complex Topography for Geomorphological Research

“…extraction of quantitative elevation information from stereophotography under the umbrella term photogrammetry has been shown to have much potential for geomorphological study (Chandler and Cooper, 1988;Chandler and Moore, 1989;Kirby, 1991;Lane et al, 1993Lane et al, , 1994aDixon et al, 1998). Some of the earliest applications of photogrammetry were motivated by geomorphology; the past 30 years have seen increasing use of photogrammetry in geomorphological situations, with examples including slope stability (Wickens and Barton, 1971;Fraser, 1983;Chandler, 1989), glaciology (Small et al, 1984;Brecher, 1986), coastal studies (Kidson and Manton, 1973) and river channel studies (Welch and Jordan, 1983;Lane et al, 1994a). Concurrently, developments in photogrammetry, notably the shift to fully automated, digital methods (Brunsden and Chandler, 1996;Pyle et al, 1997;Butler et al, 1998) are making photogrammetry an increasingly cost-effective option (Chandler and Padfield, 1996).…”

Indeed, growing numbers of geomorphologists are making use of these methods, often without the traditional collaboration with trained photogrammetrists which has characterized previous applications of photogrammetry to geomorphology (Small et al, 1984;Lane et al, 1994a;Chandler and Brunsden, 1995). However, as Cooper (1998) argues, the ease with which terrain data may be generated using these developments may have focused attention more on analysis and interpretation of the results acquired, than on issues of data quality.…”
