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

摘要: Recent and future climate change may lead to landscape changes in geomorphic processes process rates. Such modifications are likely be widely distributed, making their direct measurement difficult there almost no such measurements at decadal intervals. Aerial imagery has been acquired by many national agencies since the 1950s significant archives remain. Unlocking information from these data sources is important because timescale inform unresolved hypotheses regarding impact of rapid on Alpine environments. However, photogrammetric applications challenging topographic complexity (including occlusions large elevation ranges) variations image texture. A complete workflow described raw treatment interpretation results. This applied Val d'Herens, Switzerland, a containing an assemblage glacial, periglacial, hillslope fluvial landforms across height range 1800 3600 m 1960s present. These reveal characteristics scale erosion deposition scale.
