Hi!

The second round of the Sentinel Hub Custom Script Contest is in full swing. Learn more about it and find out how to make your scripts more efficient. If you are interested in using Python to fetch, store and analyze satellite data, take a look at the newly available Sentinel Hub xcube Python package. This and much more awaits you in today's issue.

In case you are participating AWS re:Invent conference, don’t forget to reserve your seat for our BlueDot Water Observatory session on 4 December and learn how you can make a global project more cost effective than ever before.


 

 
 

The Sentinel Hub Custom Script Contest

 

Share your awesome algorithms and win attractive prizes!

Join the second round of our Custom Script Contest and hand in up to three different scripts for the Sentinel Hub EO Browser until January 15, 2020. All the entries will compete under one common category and will be judged by a jury of experts on functionality and usefulness, as well as possible commercial potential. The best three custom scripts will be awarded cool prizes.

BlueDot at AWS re:Invent Conference

A cost-effective and reliable solution for monitoring water resources will be presented at the biggest event in the cloud community in the world.

The BlueDot Water Observatory is an Earth-observation-based solution that provides reliable and up-to-date information on surface water levels around the world. Today it already includes more than 13 000 water bodies. To learn more about the technology behind it, attend our Monitoring the Earth Without Costing the World presentation at the AWS re:Invent conference in Las Vegas, Nevada on Wednesday, December 4, 2019. We will show you how to use global satellite imagery stored on Amazon S3 in combination with an efficient use of services such as AWS Lambda, Amazon DynamoDB and Amazon CloudWatch.

Identifying Fake Satellite Images

A guest blog post by Pierre Markuse.

Have you ever wondered if the satellite images you see in the media are genuine? Check out this insightful blog post which analyzes satellite imagery and helps you understand which imagery is real and which could be fake. It contains important guidelines for the media in dealing with stories using satellite imagery.

Introducing the DisplayWall

Create awesome slideshows with your favorite satellite imagery and display them on a big screen.

The DisplayWall is a web application for showing satellite images of locations that you save as pins in EO Browser. It is perfect for touch displays mounted on walls. It is build on top of Sentinel Hub services which provide the latest scenes the moment they are available. This enables one of the DisplayWall’s most important features — its dynamics. To create your list of preferable locations and visualizations all you need is EO Browser where you can access more than 7 PB of satellite data, both historic and the latest acquisitions, increasing at a rate of about 300 TB every month.

Sentinel Hub Integration with xcube

We are happy to announce that the Sentinel Hub was successfully integrated with xcube.

xcube is an open-source Python package and toolkit, which enables the generation, manipulation, analysis, and publishing of data cubes from Earth observation data. With this integration in place, it becomes very easy to fetch any data offered by Sentinel Hub and store it in xcube. This includes custom data registered in Sentinel Hub with BYOD functionality. xcube is based on xarray and supports complex data analysis. Together with the ability to efficiently include vector data in the analysis makes it complementary to Sentinel Hub services.

This work is part of the European Data Cube Facility Service project mentioned in one of our previous blog posts. For more on examples and installation we recommend reading the xcube documentation.

 
 

New Feature: Batch Processing

Coming soon!

The moment when you can run your evalscripts on a arbitrarily large areas is soon approaching. This feature is still in Beta. We can't promise anything, but if you have a specific use-case in mind, contact us and you might get a sneak peek.
