Get ready! The new special edition of Sentinel Hub Custom Script Contest – Urban Growth in Africa – focusing on change
detection and urban growth will launch in late April / early May 2021. We will publish more information soon!
Sentinel Hub Custom Script Contests
Remote sensing is making its way into more and more applications and fields. Tools like
the Sentinel Hub EO Browser with its custom scripting allow all people to browse, analyse and
visualise satellite data in almost real-time.
Together with our partners, the Copernicus EU Earth Observation programme,
the European Space Agency, AI4EO consortium and
Euro Data Cube (EDC) we are looking for new and innovative ideas and scripts.
Therefore, we have organized a series of the Sentinel Hub Custom Script Contests starting with the first one
in Spring 2019 and following with the second one in Winter 2019/2020. In April and May we have organized a special
edition of the Contest - the Covid-19 Custom Script Contest. It was aiming to help the world facing huge challenges
getting back to ‘normal’ after the coronavirus Covid-19 pandemic. The success of the series motivated us to continue
with the third edition of the Contest in Summer 2020.
The new special edition of Sentinel Hub Custom Script Contest – Urban Growth in Africa – focusing on change
detection and urban growth will launch in late April / early May 2021. More details about this edition will be published
on this page in the coming days.
The third round of the Contest introduced a new challenge (optional), with dedicated prizes. To qualify for it, besides
the already known requirements, scripts had to be based on a machine learning workflow developed
using eo-learn - a collection of open source Python packages
to seamlessly access and automate the processing of spatio-temporal image sequences acquired by any satellite fleet.
You can find an example of such script
Ideally participants contributed to the code-base during the contest.
We wanted the Contest to be completely open. So, all the submitted scripts competed under one common category no matter
for which data collection (Sentinels, Landsat, etc.) the scripts were used for, or if the script was eo-learn-based or
not. Many scripts could run in different categories anyway, so it was just fair to compare them to all scripts handed
How to Create a Script?
If you need some help and instructions on how to get started with custom scripting for the EO Browser we suggest you read:
In addition to above, special prizes were awarded to:
the best eo-learn-based script: 700 EUR
the best custom script submitted by a high-schooler or a high-school team: 300 EUR + a box of goodies large enough
for all team members - There wasn’t any submissions received from a high-scooler or a high-school team.
Among all the early bird submissions we awarded:
the best custom script with 500 EUR
the best eo-learn-based script with 300 EUR - There wasn’t any submissions including eo-learn-based
scripts received on time.
The scripts winning the early bird awards also competed in the overall competition at the end of the Contest.
All winners will also get an opportunity to highlight their winning scripts in
the Sentinel Hub blog.
All scripts had to be handed in as text files until 30th November 2020 (23:59 CET).
The early bird submission needed to be handed in before 20th September 2020 (23:59 CET).
Together with the script, you had to hand in a proper description on what your script can be used for and explain how
it is achieving that. You could include the description in Jupyter Notebook or in a separate file.
By handing in a script, you confirmed to be the sole author(s) of the script and to have the necessary rights to do so.
Every single participant or group could hand in up to three scripts.
Remote sensing consultant. Her main interests are Earth surface deformation caused by volcanoes and earthquakes, deforestation and natural hazards. She also has a keen interest in climate change and pollution.
GIS and remote sensing at HaMaarag, Israel's National Nature Assessment Program. His special interests are wildfire damages, long-term vegetation trends, landcover and landcover change mapping, and the encroaching of buildings and infrastructure on open landscapes.
Hayley Evers-King is a marine EO scientist with a focus on Sentinel-3 and ocean colour. Hayley has worked on a wide variety of topics including water quality, ocean heat flux, and carbon pools. She is passionate about growing the use of EO data and currently supports EUMETSAT on user support and training activities for their Copernicus missions. She believes science communication is part of every scientists job and has been involved in many activities promoting EO science, from the creation of ocean MOOCs, youtube videos, and open source python tutorials, to music compositions, poetry evenings, and cooking demonstrations.
Mark Parrington is a senior scientist at ECMWF where he works with the Copernicus Atmosphere Monitoring Service development team. His scientific interests are in using observations from satellites and aircraft to understand wildfires and how their emissions impact global atmospheric composition and air quality.
Chief Technology Officer and Co-founder of Sinergise
Remote sensing scientist with specific interest in the use of multi-source remote sensing and land surface modelling to assess the cryosphere, atmosphere and ecosystem dynamics. Since 2016 he is assistant professor of Geoscience & Remote Sensing at the TUDelft in the Netherlands.
Thomas E L Smith
Dr Thomas Smith is Assistant Professor of Environmental Geography in the Department of Geography & Environment at the London School of Economics. Dr Smith is particularly interested in complex interactions between agricultural practices, land degradation, wildfires emissions and their associated impacts.
Global applicability (scripts, which can run on different parts of the world rank better)
When and how will I be informed about results?
We will announce the winners of the Contest on this web page latest on 30th November 2020. However, everyone will
also be informed by e-mail within 3 working days after the announcement.
Can I base the script on a publicly available research paper?
Yes, of course. We believe there is a lot of useful research available in the EO domain and it should be used to
all extent. You should however appropriately credit the work in the accompanying document.
Do I need to subscribe to Sentinel Hub to participate in the Contest?
No. EO Browser is a free tool. In case you need some advanced
features (e.g. time-lapse, comparison, etc.), you can create a free account.
If you would actually require Sentinel Hub web services to fine-tune your script, you can use
a 30-days free trial option or simply send us
an e-mail and we will
ensure you can do your work.
All the scripts that were submitted to the Contest in Spring 2019 were classified in one of the categories below and
added to the GitHub (see results below for direct links).
The winners of the contest were announced during
the Living Planet Symposium in Milan on
May 15th 2019 and informed by e-mail the day after.
The authors of the best scripts won attractive prizes, and the author of the overall best script got an invitation to
visit the European Space Research Institute (ESRIN), home of ESA’s center for
Earth Observation, to discuss his script with experts in the relevant fields.
European Space Agency (ESA), in coordination with
the European Commission, has launched a special edition of the Custom Script Contest, focused
on the support of space assets during the COVID-19 crisis, managed by Euro Data Cube
group. Following a similar format, but further to looking for new algorithms, we were in the quest for ideas on how
satellite data could help monitor and mitigate the situation after the coronavirus Covid-19 pandemic. During the
Contest (from 6th of April to 31st of May 2020) we have received many interesting ideas and proposals from remote
sensing experts, machine learning scientists and the interested public.
The best ideas were presented to the European Commission in the context of the dossier ESA is preparing
on space as a support to Covid-19 situation in the EU. Read more about the winning scripts of RACE Upscaling Competition
in one of our blog posts.
Results of the Third Custom Script Contest
The third Contest started on August 4th 2020 and ended on November 30st 2020. All entries were judged by a jury of
experts on functionality and usefulness, as well as possible commercial potential.
The winning scripts will be highlighted on our Sentinel Hub Blog in coming weeks.
So, stay tuned!
