Take part in the Sentinel Hub Custom Scripts Contest!

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.

We at Sentinel Hub, together with our data partners, the Copernicus EU Earth Observation programme and the European Space Agency, are looking for new and innovative ideas and scripts. Do you think you have what it takes to write a useful custom script for the EO Browser? Then take part in our Custom Script Contest. You can hand in up to three different scripts either as a single author or as a representative of a group. We strongly encourage the participation of students, be it a university or high school. The contest could be an interesting project for high school science classes.

Win a trip to ESRIN in Rome!

Starting today until May 5th you can hand in custom scripts for the Sentinel Hub EO Browser in one of the categories below. All the entries will be judged by a jury of experts on functionality and usefulness, as well as possible commercial usefulness. The authors of the best scripts will win attractive prizes, and the author of the overall best script will be invited to visit the European Space Research Institute (ESRIN), home of ESA’s centre for Earth Observation, to discuss their script with experts in the relevant fields.

  1. Agriculture and Forestry
  2. Marine environment
  3. Snow and Glaciers
  4. Disaster management and prevention (wildfires, floods, hurricanes, …)
  5. Air quality and Urban planning
  6. Other scripts (all not fitting into one of the other categories)

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:

Attractive Prizes

For each of the categories:

  • First prize: 1.000 EUR + 1-year Enterprise Sentinel Hub account (worth 5.000 EUR) + some nice goodies
  • Second prize: 300 EUR + 1-year Individual commercial Sentinel Hub account (worth 1.000 EUR) + some nice goodies
  • Third prize: 1-year Individual commercial Sentinel Hub account (worth 1.000 EUR) + some nice goodies

Additionally, the best Sentinel-1 (SAR) script will win 500 Euro and goodies, and the second and third best will also get some goodies.

The best overall script will win a trip to the European Space Research Institute (ESRIN) in Rome, travel and two nights in a hotel included, sponsored by ESA, the opportunity to talk with experts in relevant fields and to see the Phi Experience, opening up exciting insights into modern Earth observation.


Natural color view of wildfires in California in 2017. Hot spots highlighted to show possible active fires. View script in EO Browser.

How to participate?

  1. All scripts must run within the Sentinel Hub EO Browser.
  2. All scripts have to be handed in as text files until May 5th 2019 (23:59 CET) . Together with the script, you have to hand in a description on what your script can be used for and explain how it is achieving that. In case your script is based on other people’s work make sure to include the necessary citations and links to relevant papers. Submit your scripts here
  3. By handing in a script you confirm to be the sole author(s) of the script and to have the necessary rights to do so.
  4. Every single participant or group can hand in up to three scripts, however, not more than one script per category is allowed.
  5. All entries must be licensed under the Creative Commons BY license, so they can be added to the custom scripts repository and be used freely by all.

  • When and how will I be informed about results?
    • We will announce the winners of the contest during the Living Planet Symposium on 15th of May at 18:00 CET (Metallo Agora room). Contest participants, who will be at LPS 19, are welcome to attend. However, everyone will also be informed by e-mail latest one day after the event.  


  • 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.



  • My script stops working after it becomes too long.
    • There is indeed a technical limit on number of chars, which can be passed over HTTP. But no worries, there is a simple way to solve it.


  • I am more interested in sharing knowledge than a monetary prize. Should I still participate?
    • Of course, this is the main objective of this contest. In case you do not want to receive the prize, you can name a philanthropy organisation of your choice and we will donate the amount to them.


  • Can I submit scripts, which just look nice?
    • Main goal of this action is to share knowledge. However, art is important as well and we need to be aware of the beauty of our Planet, so go ahead!  


  • If I do not win the prize, will my script still be added to the Custom script repository?
    • We plan to add all scripts, which seem sound, to the repository. We will also be publishing a stream of short blog posts about all interesting scripts. 


  • I have submitted a script but now I want to correct it. What to do?
    • No problem. Simply submit a new version of the script and state very clearly at the beginning that this submission is replacing a previous one.


  • If I win a trip to ESRIN, can I extend it to visit also Rome and surroundings?
    • Sure. You will have to cover additional costs yourself, but we are flexible with the plane ticket schedule.


  • Where can I get more information?
    • Ask a question on our Forum and we will respond.
