Landsat-8 on AWS Reader

Licensing options for this format begin with FME Desktop Professional Edition.

The Landsat-8 on AWS Raster reader provides FME with access to data in the Landsat-8 format stored on Amazon Web Services (AWS).


Landsat-8 is an Earth-imaging satellite administered by the United States Geological Survey (USGS). The Landsat 8 satellite carries two instruments: the Operational Land Imager (OLI) and the Thermal Infrared Sensor (TIRS). Data is provided as 11 grayscale bands at a depth of 16 bits, along with a quality assessment band, also at 16 bits. However, sensor resolution is only at 12 bits, or 4096 gray levels.

The data is available at no charge directly from the USGS.

For more information about Landsat 8, please see Specifically, for information about interpreting the quality assessment band, see

Landsat-8 AWS Data

As part of a public datasets initiative, Amazon Web Services (AWS) has partnered with NASA and the USGS to provide Landsat-8 data free-of-charge on AWS S3. The Landsat-8 on AWS reader provides access to this resource. It has all the functionality of the underlying Landsat-8 Reader, with additional search capabilities particular to the AWS dataset. The imagery can be searched by date and geographic area of interest.

All Landsat-8 data from 2015 onward is available, along with some cloud-free scenes from 2013-2014.

Reader Overview

The Landsat-8 on AWS Raster Reader downloads Landsat-8 data from Amazon S3 based on a spatial filter and a date filter.

Note: On Windows, this format caches downloads in the temp folder. FME attempts to limit the size of the cache based on the value specified in the Cache Limit field under Tools > Options > Translation> Web File Cache.

FME Raster Features

FME raster features represent raster data and use several concepts that are unlike those used in the handling of vector data. The topics below describe how FME processes raster data.
