SIGN IN

Hi there!


After another productive period, we have exciting updates for you! If you are a fan of 3D satellite imagery, you'll be happy to hear that EO Browser got another big update to the terrain mode. Also, read about the newly added Zarr input format, the latest blog post on area monitoring, newly available collections, Euro Data Cube updates and more. Do not miss registering for our next webinar - Bring Your Own Data - which will be live next week.

And for the end, perhaps an interesting titbit for those of you who are interested in our internal work - to serve you all, there are about 175 million requests processed internally on an average day.



 

Data Collections Keep Expanding

Six new collections have been added to Sentinel Hub

If you missed our announcement in October, this will brighten your day. The newly released ESA WorldCover collection can serve as an essential input for various machine learning exercises. We also added the CORINE Land Cover Accounting Layers collection and four collections that allow you to browse high-resolution vegetation indices, as well as phenology and productivity products. You can find all six collections in the Sentinel Hub Public Collections registry or view them directly in EO Browser under Copernicus Services.



 

EO Browser Updates

Three new features and twice as many new collections added

It was not that long ago that we introduced a brand new 3D engine for the terrain viewer in EO Browser. And we already have an update for you: It is now smoothly integrated into the overall user interface, allowing you to switch directly between visualizations, dates and collections in 3D mode via the familiar sidebar. In addition, EO Browser now offers basic image download for images in compare mode and has a smarter search bar that not only takes you to the selected location, but also zooms the map to an appropriate extent.

Area Monitoring: Pixel-level Mowing Marker

When an object-based approach is not good enough

c9246288-4f4c-11e9-a3c9-06b79b628af2%2F1636369760528-pixel-mowing-nl-lc.gif

Mowing event detection is one of the most important aspects of area monitoring due to impact of grasslands to the biodiversity. A good and reliable algorithm is crucial to help authorities in decision making. Lots of methods have troubles with partial mowing events. In such cases, one of the solutions is pixel-level detection. Check our blog post to read about how we solved this problem in our Area Monitoring project!


 

New Sentinel-3 OLCI Bands on CreoDIAS

Our Sentinel-3 OLCI band collection now also has the five azimuth and zenith bands at 19 km resolution on CreoDIAS. The new bands are called Sun azimuth angle (SAA), Sun zenith angle (SZA), Viewing (observation) azimuth angle (VAA) and Viewing (observation) zenith angle (VZA). For more information about the Sentinel-3 OLCI bands, see our data documentation.

Bring Your Own COG Update

Support for multi-band COGs and custom band names

BYOC now supports multi-band COGs. To learn how to configure a collection with such files, see our documentation. We have also added the option to name your bands differently than the file names. You can easily do this in Sentinel Hub Dashboard or using the API. Details on how to do this via the API can be found here.


 

Zarr Input Format Support

Sentinel Hub now allows you to bring in your own data in Zarr format. Zarr is a cloud-optimised method for storing chunked, compressed, N-dimensional arrays and is commonly used in certain fields, such as climate research.

Sentinel Hub supports Zarr groups with two-dimensional and three-dimensional (with time) geolocated data arrays. Your Zarr data will need to be stored on AWS or CreoDIAS. They can then be ingested and used similarly to the existing Bring-Your-Own-COG functionality, but with some important differences due to the properties of the Zarr format. For details, see the documentation and API reference.

Best Custom Script and Written Story

Guest blog posts from the winners of the Sentinel Hub Custom Script Contest

We are pleased to present the winning entries from our latest Sentinel Hub Custom Script contest - Urban Growth in Africa - which ended in September. The authors of the best custom script and best written story using Earth Observation data take us behind the scenes of their entries. Read their blog posts:

OpenEO Platform

Project update

c9246288-4f4c-11e9-a3c9-06b79b628af2%2F1637756198869-openEO-logo.pngTogether with our project partners (EODC, EGI, EURAC, GEO, Vito, WWU Münster) we built the openEO Platform - a new cloud processing environment for large-scale analysis of EO data. It brings together the extensive archives of Terrascope, Sentinel Hub via the Euro Data Cube, CreoDIAS and EODC and gives you access to all these backends through a single interface. Depending on your skills and preferences, you can connect to the platform via easy-to-use programming libraries (Python, JavaScript, R) or the JupyterLab and openEO Platform Editor development environments.

During ESA Phi-Week last month, we presented the first year's progress and the platform in BETA was opened to early adopters in a public launch event. Learn how to participate and apply for an ESA-funded package here.


 

Euro Data Cube Update

View public EDC Collections and order custom data on demand

c9246288-4f4c-11e9-a3c9-06b79b628af2%2F1624350990955-EDC_symbol_blue.pngThe Bring Your Own Algorithm (BYOA) offering is now fully operational, enabling anyone in the Earth Observation community to deploy and market their algorithms on the Euro Data Cube platform. The EDC Marketplace already provides access to several algorithms in Insights on Demand. We are also closing working with other algorithm owners. So be sure to look out for new offerings in the coming months.

We’d be delighted to see the community bringing own algorithms to the platform. With EDC's technology and cloud processing, you can create multitemporal applications like deforestation detection and then run them at scale, for example for the whole of Europe. To help you develop your algorithms, we also provide several datasets in EDC Public Collections, such as the Vegetation Indices collection, which contains four widely used indices.

If you have an algorithm that you would like to include in the Euro Data Cube platform, we would love to hear from you, regardless of what stage of development you are at. So get in touch with us via a bot on the EDC website!
