Overview

This data set, part of the NASA Making Earth System Data Records for Use in Research Environments (MEaSUREs) program, contains high resolution mosaics of radar backscatter for the Greenland Ice Sheet derived from synthetic aperture radar (SAR) data. Both calibrated and uncalibrated mosaics are available for: the winters of 2000-2001, 2005-2006 through 2008-2009, and 2012-2013; and a multiyear composite. Uncalibrated mosaics are available for the winter of 2009-2010. All mosaics are provided at both 100 m and 20 m resolutions. See Greenland Ice Mapping Project (GIMP) for related data.

How To

The answer is yes. Below the image in this article, you will find  sample code in IDL, MATLAB, and Python to read in a GeoTIFF file, extract the metadata, and create an image. The code has been tested with data from:
We recommend using the Geospatial Data Abstraction Library (GDAL) to convert GeoTIFF files into a different format.
We recommend using the Geospatial Data Abstraction Library (GDAL) or a GIS to reproject geoTIFF files.
