Sentinel-1 data now available on AWS

Multi-looked image on Sentinel-Hub from AWS.

Europe: Sentinel-1 data are available on the Open Public Dataset at AWS, hosted on eu-central-1 in Frankfurt, Germany. The dataset currently contains the data from 1st of May 2017, and it is regularly synchronized with OpenHub.

The dataset currently contains the data from 1st of May 2017, and it is regularly synchronized with OpenHub. The company has also re-encoded the imagery data on AWS to cloud-optimized GeoTIFF to make the data more accessible and cloud processing friendly. The files have embedded multi-looked overviews as well, which allow for fast access to high-quality data at lower resolutions.

Sentinel Hub services also offer Sentinel-1 GRD data from AWSS which is considerably more difficult to display than other satellites in real time. Each pixel in an image needs to be converted to meaningful physical quantities and geopositioned individually. There is no global mapping which can take care of this. Orthorectification is even more complicated as it requires the use of a digital elevation model, and again, adjusted for each pixel individually.

The fast AWS architecture and cloud-optimized GeoTIFFs allow for faster response times compared to the current service running on a different platform with original, non-cloud-optimized files.
