Despite the hot summer weather in recent weeks, our work has not slowed down. So, before the summer really gets going, we are sharing the latest updates with you. In this issue, read all about the value of super resolution imagery, progress on Area Monitoring, new features in EO Browser, the announcement of the Asynchronous Process API, other Sentinel Hub updates, the release of HIECTOR and more. In addition, the deadline for the Sentinel Hub Climate Change Custom Script contest has been extended.
Parcel boundary detection with super-resolved satellite imagery
Our research team's experiment attempts to determine the value of super resolution (SR) imagery in a real-world use case - parcel boundary detection. It looks at the advantages and disadvantages of both SR and original Sentinel-2 source, and raises questions about the (lack of) interpretability of super-resolved imagery.

We have learned a lot in setting up the Area Monitoring for Slovenia 2021; it has been a bumpy but exciting journey. In our latest blog post, we summarise the highlights of the process over the past year. In it, we show how the satellite data, calculated markers, and experts' assessments every two weeks, were brought together to allow the paying agency to review inconclusive parcels more efficiently. Check it out and let us know what you think!
Participate in the special edition - Climate Change
The deadline to submit your awesome scripts or stories has been extended until September 11th. You can hand in up to three different scripts which run in Sentinel Hub EO Browser and/or write a story focused on how to communicate climate change using EO data.
This edition of the Sentinel Hub Custom Script Contest is organized in partnership with the European Space Agency (ESA) and the World Meteorological Organization. The goal of this activity is to demonstrate the power of EO data in detecting the effects of climate change. See our official contest page for details!
One new collection, two new languages and three new features added!
CNES land cover map - a collection covering metropolitan France with a 10 meter spatial and annual temporal resolution - has been added. Speaking of France, EO Browser is now available in French, providing easy access to the nearly 100 million native French speakers around the world. We have also added support for Latvian, bringing the total number of supported languages to 10, with more to come soon.
In terms of features, we now support image download and time-lapse for the Planet NICFI collection, WKT geometry in AOI upload, and extended advanced options (3D elevation model selection and backscatter coefficient selection for Sentinel-1).
Asynchronous Process API
We are developing an asynchronous equivalent to the Process API, intended for larger requests where you don't need the results immediately. It will work similarly to the Process API, with the difference that:
- Limitations on resolution, output raster dimensions, and time interval of input data will be relaxed.
- One specifies the object storage the results should be stored when the request is submitted.
- Later, a notification mechanism will be added to inform of completion. Until then, one can query the API for the status of your request(s).
The new service is scheduled for release at the end of the year, but select customers will be able to test it earlier. If you are interested, let us know.
Released and open-sourced
Learn how to cost-effectively extend building detection to large areas. HIECTOR performs hierarchical object detection using satellite imagery with increasing spatial resolution, using (costly) high-resolution imagery only where needed. We show how using detection on Sentinel-2 can save more than 60 % of the cost, with negligible loss of accuracy. Read the blog post for details on the open source code base and pre-trained weights of the deep learning models. HIECTOR was developed as part of Query Planet, funded by ESA/ESRIN philab.
The last few weeks have been very busy for the Euro Data Cube (EDC) team. We presented several EDC services at the Living Planet Symposium in Bonn, including a packed workshop on leveraging the EDC. The workshop notebook is now available through the EDC marketplace.
In the meantime, we have also been crunching big data using EDC; running Henrik Fisser's Truck Detection algorithm for the whole of Europe for the years 2020 and 2022. This data will soon be available to view and download via the RACE dashboard.
Other Sentinel Hub Updates
- The Copernicus DEM has been upgraded to the latest release - 2021 - on Sentinel Hub and AWS.
- Sentinel Hub CARD4L Sentinel-1 processing has been officially confirmed as CARD4L-compliant.
- Statistical API was promoted from Beta to fully operational status.
- BYOC tiles created from the imported third-party data can now be listed using API as well as in the dashboard.
It was a pleasure to meet many of you in person at ESA’s Living Planet Symposium in Bonn this May. Every three years the event - one of the largest of its kind - attracts brilliant minds, scientists, technical experts and researchers, all from the EO and surrounding fields. Our team from Slovenia and Austria held a variety of activities, including talks, presentations, demos, trainings, and poster sessions. Read more about it in our news post.
We are honoured to have spoken in the opening ceremony.
We hope to see you in person soon. Mark your calendars for our presentations at the following events:
Feel free to send us your feedback via the Forum or social media. We look forward to hearing from you.
