2000 Greenland Mosaic - Greenland Ice Mapping Project (GIMP) (OSU/GIMP/2000_IMAGERY_MOSAIC)
Version 1
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.
| Name | Description | Gee Wavelength | GSD (m) |
|---|---|---|---|
| B1 | Landsat 7 ETM+ blue | 0.45 - 0.52 µm | meters |
| B2 | Landsat 7 ETM+ green | 0.52 - 0.60 µm | meters |
| B3 | Landsat 7 ETM+ red | 0.63 - 0.69 µm | meters |
| B4 | Landsat 7 ETM+ near infrared | 0.77 - 0.90 µm | meters |
| B5 | Landsat 7 ETM+ shortwave infrared 1 | 1.55 - 1.75 µm | meters |
| B6_low_gain | 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. | 10.40 - 12.50 µm | meters |
| B6_high_gain | 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. | 10.40 - 12.50 µm | meters |
| B7 | Landsat 7 ETM+ shortwave infrared 2 | 2.08 - 2.35 µm | meters |
| B8 | Landsat 7 ETM+ panchromatic | 0.52 - 0.90 µm | meters |
| B8_radarsat | RADARSAT-1 synthetic aperture radar amplitude imagery | meters |
