Polar Satellite Imagery Resources
Last Updated: March 29, 2018
PGC maintains a list of external (non-PGC) polar satellite imagery resources.
While PGC provides a distinct set of polar satellite imagery, namely commercial satellite imagery from DigitalGlobe, there are many other imagery resources available.
The list below is non-exhaustive, but is a curated list of repositories and data sets that PGC uses and recommends. PGC does not provide support for using any of these datasets.
If you are a polar imagery provider and would like to add your organization to this list, we would love to add you! Just send us a message with details.
MODIS and Suomi-NPP
MODIS (Terra and Aqua) and Suomi-NPP products collect coarse-resolution (250-meters) of the Earth daily. There are many scientific products included with these datasets, including corrected reflectance, fires, vegetation, and air quality (among others). Data collection and the Worldview portal (not to be confused with DigitalGlobe’s WorldView sensors) are maintained by NASA.

The Landsat sensors have been continuously imaging the Earth since the 1970s. The most recent sensor, Landsat 8, was launched in 2013. Landsat is maintained by NASA and the USGS.

Landsat Image Mosaic of Antarctica (LIMA)
LIMA is a 15-meter optical imagery mosaic of Antarctica released in 2001 from over 1,000 Landsat 7 ETM+ imagery scenes, corrected and color-balanced. LIMA was produced as an international partnership between NASA, USGS, NSF, and BAS.

The Sentinel constellation includes sensors which collect medium-resolution imagery. Sentinel-2 collects optical satellite imagery at 10-meter resolution. Data collection and the Copernius Open Access Hub (registration required) are maintained by the European Space Agency.

Polar View is a resource for Arctic and Antarctic sea ice data. Datasets include Synthetic Aperture Radar (SAR) imageyr, sea ice concentration, ice charts, and ice edge data. Polar View is maintained by the British Antarctic Survey.
