Custom Script Contest

The Sentinel Hub Custom Script 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 constantly looking for new and innovative ideas and scripts. Therefore, we have organized the first Sentinel Hub Custom Scripts Contest (March - May 2019) where participants shared useful custom scripts for the EO Browser. They were handing in up to three different scripts either as a single author or as a representative of a group. We are pleased to see many students among the participants and we hope that the contest becomes an interesting project either for high school or university science classes in the future.

Results

All the scripts that were submitted to the Contest were added to the GitHub (see results below for direct links). We will also write some blog posts on this topic so follow us on Twitter and Medium!

Winning a trip to ESRIN in Rome!

The custom scripts for the Sentinel Hub EO Browser were classified in one of the categories below. All the entries were judged by a jury of experts on functionality and usefulness, as well as possible commercial usefulness. 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 centre for Earth Observation, to discuss his script with experts in the relevant fields.

Categories

  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)

Creating Scripts

Some help and instructions on how to get started with custom scripting for the EO Browser:

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 won 500 Euro and goodies, and the second and third best also got some goodies.

The best overall script won 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.

Rules

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