Sentinel-2 on AWS Reader

Licensing options for this format begin with FME Professional Edition.

The Sentinel-2 on AWS Raster reader provides FME with access to data in the Sentinel-2 MSI SAFE format stored on Amazon Web Services (AWS).


The European Space Agency’s Sentinel-2 is an imaging mission involving satellites carrying the Multispectral Instrument (MSI). The MSI captures images in 13 spectral bands at resolutions of 10 metres, 20 metres, and 60 metres. It is designed to be used for applications such as spatial planning, environment & water monitoring, and forest & vegetation monitoring.

Sentinel-2 MSI SAFE Level-1C products are comprised of a folder structure containing a manifest file as well as subfolders for image data, product information in XML format, and other metadata. Level-1C products contain a single data-take, which is a continuous acquisition of image data. A data-take is comprised of granules or tiles, which divide the entire capture area into smaller regions. Each tile is stored as a set of JPEG-2000 images, each image containing the data for one of the 13 spectral bands.

The reader supports UTM coordinate systems in the dataset. A raster may contain tiles that cross UTM zone boundaries, but the raster will be treated as belonging to one zone.

Each SENTINEL2AWS dataset produces a single feature per resolution. A dataset is classified by a Military Grid Reference System (MGRS) ID, a date, and a sequence number in the event that more than one image sequence was taken on a particular day in a region. A grid square is a combination of UTM zone, UTM/MGRS latitude band, and MGRS square identifier. A grid zone is a combination of UTM zone and UTM/MGRS latitude band.

Reader Overview

The Sentinel-2 on AWS Raster Reader downloads Sentinel-2 data from Amazon S3 based on a spatial filter and a date filter.

FME Raster Features

FME raster features represent raster data and use several concepts that are unlike those used in the handling of vector data. See About FME Rasters.
