AI-generated Key Takeaways
-
This collection of datasets from the Greenland Ice Mapping Project (GIMP) provides comprehensive coverage of the Greenland ice sheet, including land ice and ocean masks, image mosaics, and a digital elevation model (DEM).
-
The datasets are derived from various sources like Landsat 7 ETM+, RADARSAT-1 SAR, ASTER, SPOT-5, and AVHRR, offering a multi-sensor perspective on the ice sheet.
-
GIMP data enables analysis of ice cover, surface features, topography, and glacier velocity, crucial for understanding ice sheet dynamics and climate change impacts.
-
The datasets are available at resolutions ranging from 15m to 1km, facilitating detailed investigations and large-scale assessments.
-
Part of NASA's MEaSUREs program, these datasets provide valuable insights for research and monitoring of the Greenland ice sheet.

2000 Greenland Mosaic - Greenland Ice Mapping Project (GIMP)
This dataset provides a complete 15 m resolution image mosaic of the Greenland ice sheet derived from Landsat 7 ETM+ and RADARSAT-1 SAR imagery from the years 1999 to 2002. The methods include a combination of image cloud masking, pan sharpening, image sampling and resizing, … arctic gimp greenland imagery nasa polar -
Greenland DEM - Greenland Mapping Project (GIMP)
This Digital Elevation Model (DEM) is constructed from a combination of ASTER and SPOT-5 DEM's for the ice sheet periphery and margin (i.e. below the equilbrium line elevation) south of approximately 82.5°N and AVHRR photoclinometry in the ice sheet interior and far north (Scambos and … arctic elevation-topography gimp greenland nasa polar -
Greenland Ice & Ocean Mask - Greenland Mapping Project (GIMP)
This dataset provides complete land ice and ocean classification masks at 15 m for the Greenland ice sheet. Ice cover was mapped using a combination of orthorectified panchromatic (band 8) imagery from the Landsat 7 Enhanced Thematic Mapper Plus (ETM+), distributed by the USGS, and … arctic cryosphere gimp greenland ice nasa -
MEaSUREs Greenland Ice Velocity: Selected Glacier Site Velocity Maps from Optical Images Version 2
This dataset, part of the NASA Making Earth System Data Records for Use in Research Environments (MEaSUREs) program, consists of mean monthly velocity maps for selected glacier outlet areas. The maps are generated by tracking visible features between optical image pairs acquired by the Landsat … arctic cryosphere gimp greenland ice nasa
