چکیده

Abstract We present geodetic mass-balance estimates for ten glaciers (22.6 ± 1.1 km 2 ) around Volcán Domuyo between 1962 and 2020 (and 46 covering 29 1.5 1984 2020), derived from airborne, ASTER Pléiades imagery. Overall, we find a slightly negative mass balance (−0.15 0.09 m w.e. –1 the entire 1962–2020 time span. A closer inspection of sub-periods reveals, however, an increasingly with time. The shifted moderately positive +0.28 0.13 1984, to strongly −0.99 0.19 2012 2020. An increase in summer temperatures decrease winter precipitation during last four decades are likely drivers observed glacier changes. support this finding by implementing minimal model, relying solely on monthly air temperatures. evolution detected is consistent other sites spread across Central Andes, suggesting rapidly increasing wastage impacts occurring at geographically wider scale.

Multi-decadal mass loss of glaciers in the Everest area (Nepal Himalaya) derived from stereo imagery

Mass loss of Himalayan glaciers has wide-ranging consequences such as changing runoff distribution, sea level rise and an increasing risk of glacial lake outburst floods (GLOFs). The assessment of the regional and global impact of glacier changes in the Himalaya is, however, hampered by a lack of mass balance data for most of the range. Multi-temporal digital terrain models (DTMs) allow glacier...

Automating Image Map Generation Using Satellite Images and Aerial Photos

Image maps generated using satellite images and aerial photos are extremely useful. The map can provide detailed topographic, land-use and land-cover information on earth. With the growing number of satellite and aerial photo data, a technique which can generate/update maps automatically from satellite images and aerial photos is necessary. This paper presents a technique developed at PCI Geoma...
