  • Casey Station Footprint GIS Layers, 2002-2018

    https://cmr.earthdata.nasa.gov/search/concepts/C2102891782-AU_AADC.xml
    Description:

    This dataset contains GIS spatial layers of the medium and heavy disturbance footprint surrounding Casey Research Station at the years 2002, 2008, 2015 and 2018. The footprint mapping used a consistent methodology for digitisation for the years 2002, 2015, and 2018, whereas the year 2008 included ground-truther field measurements. Some variation in the footprint is due to snow cover hiding areas of disturbance. The sources and date of the data used is as follows: • 2018 Casey Heavy Disturbance – digitised by S. Brooks from Worldview-3 imagery, captured 27/1/2018. • 2018 Casey Medium Disturbance – digitised by S. Brooks from Worldview-3 imagery, captured 27/1/2018. • 2015 Casey Heavy Disturbance – digitised by S. Brooks from AAS 5024 UAV-imagery. • 2015 Casey Medium Disturbance – digitised by S. Brooks from AAS 5024 UAV-imagery. • 2008 Casey Heavy Disturbance – produced from data associated with: Brooks, S.T. 2014. Developing a Standardised Approach to Measuring the Environmental Footprint of Antarctic Research Stations. Journal of Environmental Assessment Policy and Management, 16(04), 1450037. • 2008 Casey Medium Disturbance – produced from aerial imagery and field data opportunistically collected in association with: Brooks, S.T. 2014. Developing a Standardised Approach to Measuring the Environmental Footprint of Antarctic Research Stations. Journal of Environmental Assessment Policy and Management, 16(04), 1450037. • 2002 Casey Heavy Disturbance – digitised by S.

  • High Mountain Asia 2 m DEM, Surface Velocity, and Lagrangian Surface Mass Balance for Select Debris Covered Glaciers V001

    https://cmr.earthdata.nasa.gov/search/concepts/C3226193732-NSIDC_ECS.xml
    Description:

    This High Mountain Asia data set contains 2 m resolution digital elevation models (DEMs), surface velocities, surface mass balance (SMB) rates, and SMB uncertainties for six debris-covered glaciers in Nepal. SMB rate is estimated by applying a Lagrangian specification to DEMs derived from very-high-resolution optical stereo imagery acquired by Maxar Technologies satellites WorldView-1, WorldView-2, WorldView-3, and GeoEye-1. This data set was granted permission for public release on 1 March 2024 under the National Reconnaissance Office (NRO) Electro-Optical Commercial Layer (EOCL) program.

  • Land Cover Classification, Snow Cover, and Fractional Snow-Covered Area Maps from Maxar WorldView Satellite Images V001

    https://cmr.earthdata.nasa.gov/search/concepts/C2695676729-NSIDC_ECS.xml
    Description:

    This data set includes: (1) fine-scale snow and land cover maps from two mountainous study sites in the Western U.S., produced using machine-learning models trained to extract land cover data from WorldView-2 and WorldView-3 stereo panchromatic and multispectral images; (2) binary snow maps derived from the land cover maps; and (3) 30 m and 465 m fractional snow-covered area (fSCA) maps, produced via downsampling of the binary snow maps. The land cover classification maps feature between three and six classes common to mountainous regions and integral for accurate stereo snow depth mapping: illuminated snow, shaded snow, vegetation, exposed surfaces, surface water, and clouds. Also included are Landsat and MODSCAG fSCA map products. The source imagery for these data are the Maxar WorldView-2 and Maxar WorldView-3 Level-1B 8-band multispectral images, orthorectified and converted to top-of-atmosphere reflectance. These Level-1B images are available under the NGA NextView/EnhancedView license.

  • MEaSUREs Greenland Ice Mapping Project (GrIMP) Digital Elevation Model from GeoEye and WorldView Imagery V002

    https://cmr.earthdata.nasa.gov/search/concepts/C2295286903-NSIDC_ECS.xml
    Description:

    This data set consists of an enhanced resolution digital elevation model (DEM) for the Greenland Ice Sheet, derived from sub-meter resolution, panchromatic stereoscopic imagery collected by the GeoEye-1, WorldView-1, -2, and -3 satellites operated by Maxar Technologies. The DEM was created from in-track image pairs (i.e., both images collected minutes apart along the same orbital pass) and cross-track images (i.e., from different orbits) within the in-track imaging geometry and maximum time separation criteria. The DEM is registered to ATLAS/ICESat-2 L3A Land Ice Height, Version 5 (ATL06, V5) data collected in the summers of 2019 and 2020. See <a href="http://nsidc.org/data/measures/gimp">Greenland Ice Mapping Project (GrIMP)</a> for related data
