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 Euro Data Cube (EDC), the Copernicus EU Earth Observation programme and the European Space Agency we are looking for new and innovative ideas and scripts. Therefore, we have organised 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 organised a special edition of the Contest - the Covid-19 Custom Script Contest. Its aim was 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. To learn more about the results of our previous contests, visit the Past Sentinel Hub Custom Script Contests page.
This special edition of the Sentinel Hub Custom Script Contest started on 3rd May 2021 and ended at midnight on 5th September 2021. The objective of this activity was to demonstrate the power of a deep multi-temporal and multi-resolution data cube combined from Sentinel-1, Sentinel-2 and Landsat. The area of interest we were looking at is Africa. To make it even more interesting, we have selected Dakar, Senegal, and loaded it with even more data - Airbus Pleiades and SPOT, Maxar WorldView/GeoEye provided by European Space imaging, and PlanetScope. Participants explored the depth and detail of so much commercial data and dense time series over a long period available for one location.
The results of the Fourth Custom Script Contest - Urban Growth in Africa - can be found at the following link:
Congratulations to all the winners and we hope to see your entries in the next Contest.
We wanted the Contest to be completely open. Therefore, all the submitted scripts competed under one common category no matter which data collection (Sentinels, Landsat, commercial data, etc.) the scripts used. We were particularly interested in scripts for monitoring change detection and growth of urban areas.
If participants didn’t have skills to create a script, they could use EO data provided to either write a matching story or create a pin story!
We were especially interested in the scripts covering one of the following:
In order to support participants, we provided a range of tools suitable for each skill level.
To create your pin story, you could either use open satellite data collections, including Sentinel-1 GRD, Sentinel-1 CARD4L, Sentinel-2, and Landsat 8, or even high-resolution commercial data collections such as Pleiades, SPOT, PlanetScope and WorldView/GeoEye data (available over Dakar, Senegal). Note that you could also select other areas in Africa to display your pin story, not just Dakar. While we only provided the high-resolution data over this specific location, you could show your pin story over other areas with the open data collections mentioned above.
EDC team provided each participant with access to a complete processing environment:
Note that you could select other areas in Africa to display the functionality of your script, not just Dakar. While we only provided the high-resolution data over this specific location, you could demonstrate the functionality of your script over other areas with open data collections. To get access to EDC tools you needed an EDC account.
Amanda O'Connor is a graduate from the University of Colorado with an M.S. in geology. She studied cross correlation of AVIRIS hyperspectral imagery and Landsat data for High Plains Vegetation Analysis in her thesis. Following graduation, she worked at Stennis Space Center on calibration projects, sensor noise simulations, and the commercialization of remote sensing. After her stint in Mississippi, she headed west to Carnegie Institution Department of Global Ecology based at Stanford University working for Greg Asner on tropical ecology projects using AVIRIS, Landsat, Hyperion, and LiDAR. There she became an expert at vegetation remote sensing and using imagery to extract robust scientific results combining multiple data sources. She has been with Harris Geospatial for 15 years in a variety of roles supporting government, commercial, and educational customers working on hard to solve remote sensing problems. Amanda took a brief break in 2019 and joined Teledyne Brown Engineering as the Director of Geospatial Solutions 2019 to support the DESIS hyperspectral mission on the International Space Station. She served as an IEEE Geoscience and Remote Sensing Society Distinguished Lecturer. Her latest spectral passion has been with marine debris detection and using spectral imagery in aquatic environments, but really any project which can be enhanced with spectral data will find her scheming a solution.
