Across-Track and Multi-Aperture InSAR for 3-D Glacier Velocity Estimation of the Siachen Glacier
Remote Sensing, 2023 Interferometric Synthetic Aperture Radar (InSAR) remote sensing generally lacks deformation sensitivity in the along-track direction. In this proposed approach, across-track observations from conventional InSAR, using both ascending and descending passes,

Improving semi-automated glacier mapping with a multi-method approach: applications in central Asia [PDF]
The Cryosphere, 2015 Studies of glaciers generally require precise glacier outlines. Where these are not available, extensive manual digitization in a geographic information system (GIS) must be performed, as current algorithms struggle to delineate glacier areas with debris

Comparison of multiple glacier inventories with a new inventory derived from high-resolution ALOS imagery in the Bhutan Himalaya [PDF]
The Cryosphere, 2016 Digital glacier inventories are invaluable data sets for revealing the characteristics of glacier distribution and for upscaling measurements from selected locations to entire mountain ranges.

The GAMDAM glacier inventory: a quality-controlled inventory of Asian glaciers [PDF]
The Cryosphere, 2015 We present a new glacier inventory for high-mountain Asia named "Glacier Area Mapping for Discharge from the Asian Mountains" (GAMDAM). Glacier outlines were delineated manually using 356 Landsat ETM+ scenes in 226 path-row sets from the period 1999–2003,

Analysing the suitability of radiometrically calibrated full-waveform lidar data for delineating Alpine rock glaciers [PDF]
ISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2013 With full-waveform (FWF) lidar systems becoming increasingly available from different commercial manufacturers, the possibility for extracting physical parameters of the scanned surfaces in an area-wide sense, as addendum to their geometric ...

Characterization of recharge components for delineation of a high-alpine rock glacier spring catchment, Ötztal Alps (northern Italy). [PDF]
Hydrogeol JAbstract Rock glaciers provide shallow groundwater reservoirs that affect the hydrology of alpine headwater catchments. However, quantifying and identifying their temporally dominating recharge components, as well as delineating their hydrological catchment, can be challenging.
