The Landsat Arctic App is powered by ArcGIS Server using the Amazon Web Services (AWS) Cloud. Landsat Arctic Views provide access to 30m 8-band multispectral services and a range of functions that provide different band combinations and indices. Landsat Arctic Pansharpened provides access to 15m 4-band (Red, Green, Blue and NIR) panchromatic sharpened imagery. You can build your own combination of bands for viewing.
