Description

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, and image coregistration. Please see Howat, 2014 for more information regarding processing methods.

Note

• Users of GIMP DEM or GIMP 2000 Image Mosaic images may find it helpful to mask out areas outside of the Greenland coastline using the corresponding 15 m ocean mask image Greenland Ice Mapping Project (GIMP) Land Ice and Ocean Classification Mask,
• The SAR data are distributed at 20 m resolution. Data were up-sampled through bilinear interpolation to 15 m to match the resolution of Landsat band-8.

General documentation

Bands

Bands

Name	Pixel Size	Wavelength	Description
B1	15 meters	0.45 - 0.52 μm	Landsat 7 ETM+ blue
B2	15 meters	0.52 - 0.60 μm	Landsat 7 ETM+ green
B3	15 meters	0.63 - 0.69 μm	Landsat 7 ETM+ red
B4	15 meters	0.77 - 0.90 μm	Landsat 7 ETM+ near infrared
B5	30 meters	1.55 - 1.75 μm	Landsat 7 ETM+ shortwave infrared 1
B6_low_gain	30 meters	10.40 - 12.50 μm	Landsat 7 ETM+ low-gain thermal Infrared 1. This band has expanded dynamic range and lower radiometric resolution (sensitivity), with less saturation at high Digital Number (DN) values. Resampled from 60m to 30m.
B6_high_gain	30 meters	10.40 - 12.50 μm	Landsat 7 ETM+ high-gain thermal Infrared 1. This band has higher radiometric resolution (sensitivity), although it has a more restricted dynamic range. Resampled from 60m to 30m.
B7	30 meters	2.08 - 2.35 μm	Landsat 7 ETM+ shortwave infrared 2
B8	15 meters	0.52 - 0.90 μm	Landsat 7 ETM+ panchromatic
B8_radarsat	15 meters		RADARSAT-1 synthetic aperture radar amplitude imagery
