    Surface topography and velocities of Ngozumpa Glacier, Nepal, with links to GeoTIFFs (2017)
    PANGAEA
    Details
    Publication Date: 2023-01-13
    Description: The dataset consists of: three orthophotos and DEMs derived from Stereo Geo-Eye and Worldview imagery; and two velocity maps derived from TerraSAR-X imagery. The DEM-orthophoto pairs cover the debris-covered tongue of Ngozumpa Glacier at 5m horizontal resolution for 9 June 2010 (GeoEye-1), 23 December 2012 (GeoEye-1) and 5 January 2015 (WorldView-3). The 'annual' velocity map is based on feature tracking on images acquired on 29 January 2015 and 5 January 2016. The 'velocity difference' map shows the difference between the 'annual' values and velocities derived from images covering a minimal 'winter' period: 19 September 2014 to 18 January 2015.

    Velocity data for two tidewater glacier surges in Svalbard, 2012-2015 (2018)
    PANGAEA
    In:  Supplement to: Sevestre, Heïdi; Benn, Douglas I; Luckman, Adrian; Nuth, Chris; Kohler, Jack; Lindbäck, Katrin; Pettersson, Rickard (2018): Tidewater Glacier Surges Initiated at the Terminus.

    Publication Date: 2023-01-13
    Description: A time-series of velocity data spanning recent surges of two tidewater glaciers in Svalbard: Aavatsmarkbreen (Dec 2012-Oct 2015) and Wahlenbergbreen (Sept 2013-Oct 2015). The data were obtained by feature tracking using pairs of TerraSAR-X backscatter intensity images, typically at 11 day intervals. The GeoTiff files are spatially filtered maps of surface speed. Filenames reveal satellite beams (strips) as well as dates and times.
