Drought impact on Lac des Brenets
Switzerland is currently knowing one of its most important drought of the last 40 years. Prolonged heat and dryness conditions during late spring, summer, and early autumn of 2018 has led to drought in most European countries (see). Different lakes in Switzerland are suffering from water shortages and their water levels are declining. This is […]
Scientific collaboration with WSL & UZH
On October 15, we had a meeting with the University of Zurich/Remote Sensing Laboratories (UZH/RSL), with David Small and Michael Schaepman, to define Sentinel-1 Analysis Ready Data. Two UNIGE/GRID team members will go to Zurich in early November to discuss and initiate S1 data ingestion. On October 16-17, we had the visit of Charlotte Steinmeier, […]
ADC4SD: Supporting Armenia in Building the Armenian Data Cube
The Swiss Data Cube team has recently received a grant to support Armenian colleagues from the Center for Ecological-Noosphere Studies (CENS) and the Institute for Informatics and Automation Problems (IIAP) of the National Academy of Sciences in developing the first version of an Armenian Data Cube. The project is entitled “ADC4SD: Armenian Data Cube for […]
Special Issue on “Earth Observation Data Cubes” – Call for Papers
Dear colleagues, Remotely sensed Earth Observations (EO) data have already exceeded the petabyte-scale and are increasingly freely and openly available from different data holdings. This poses a certain number of issues in terms of volume (e.g., data volumes have increased 10x in the last 5 years); velocity (e.g., Sentinel-2 is capturing a new image of […]
Snow Cover Change in Switzerland
Today during the EuroGEOSS workshop plenary we were pleased to present the first national product generated with the Swiss Data Cube. We used 22 years of Landsat observations over the entire Switzerland to track snow cover changes using the Snow Observations from Space algorithm. We observed that in Switzerland, snow is disappearing and this phenomenon […]
SnowCover.CH: Monitoring Snow Cover changes over Switzerland using Earth Observations time-series
We have received the good news that the project “SnowCover.CH: Monitoring Snow Cover changes over Switzerland using Earth Observations time-series” has been accepted. This project jointly lead by UNIGE/GRID (Dr. Gregory Giuliani) & UZH/RSL (Dr. David Small) is supported by the UNIGE-UZH Joint Seed Funding. Since mid-December 2017 the University of Zurich and the University of […]
Automated Sentinel-2 update
The SDC team is pleased to announce that since June 10 the Sentinel-2 Analysis Ready Data archive is automatically updated every day to ensure that the latest Sentinel-2 A/B data are available in the Swiss Data Cube. We will soon also add a similar feature to the Landsat ARD archive.
SDC Hackathon on SDG6 – results
Last week during the OpenGeneva Festival, we had a three-days hackathon trying to work with the content of the Swiss Data Cube to contribute to the Sustainable Development Goal (SDG) 6 on Water. More information can be found here. It was a really nice event, appreciated by the 29 participants with positive feedbacks and some […]
Open Data Cube Initiative & SDC
The Swiss Data Cube project leader has been interview by CEOS on the benefits of Earth Observations and data cube technology with a Swiss perspective. The following video presents the Open Data Cube Initiative and various on-going implementation in Switzerland and Colombia following the work done by Digital Earth Australia: You can also have a […]

This event is jointly organised by UN Environment/GRID-Geneva and the University of Geneva/enviroSPACE with the support of NASA/CEOS. Registration: please register to the event by filling the following form: https://goo.gl/forms/Vopz3VF3vPjwc97v1 More information on the […]
Sentinel-2 available in the Swiss Data Cube
Our team has successfully pre-processed and ingested the entire Sentinel-2 A/B archive for Switzerland. This corresponds to approximately 2400 images at 10m resolution covering the entire country for the last 2.5 years. Now, more than 2TB of Sentinel-2 Analysis Ready Data are available in the Swiss Data Cube and complement the already available 33 years […]
First Sentinel-2 Snow Cover Map of Switzerland
Today, we have executed the Snow Observations from Space (SOfS) algorithm that our team is currently developing on the newly ingested Sentinel-2 Analysis Ready Data. The result is the first Sentinel-2 Snow Cover Map of Switzerland. This allows to identify different areas ranging from no snow cover to permanent snow cover during the period April-August […]
Poster – Landsat 8 Cloud-free Mosaic of Switzerland [2016]
Today we are releasing the first product generated by the Swiss Data Cube. It is an A1 format poster of the Landsat 8 cloud-free mosaic of Switzerland for the year 2016. The image is a True Color mosaic using a median value for each pixel. The final resolution of the mosaic is 30 meters. The poster […]
First scientific publication on the Swiss Data Cube
We are happy to announce that our scientific paper entitled “Building an Earth Observations Data Cube: lessons learned from the Swiss Data Cube (SDC) on generating Analysis Ready Data (ARD)” has been published today in the inaugural issue of Big Earth Data journal. You can find the article at: http://www.tandfonline.com/doi/full/10.1080/20964471.2017.1398903 Citation: Giuliani G., Chatenoux B., De Bono […]
Urbanization – Basel 2000/2016
The Basel Region (North-western Switzerland) is an economically active region of Switzerland and urbanisation is changing rapidly the landscape of this area. We run the Urbanization algorithm to compare year 2000 and 2016 using Landsat 7 data. We can clearly see important changes in a short period of time over several parts of the region.
Urbanization – Bulle 2000/2016
In recent years, the city of Bulle (in the Fribourg canton) is an economically active region and knows an important urbanization. We used the Swiss Data Cube to try to see the urban expansion of this city. The result below allows comparing year 2000 and 2016. We clearly see the expansion of Bulle (even if it […]
First cloud-free mosaic for the entire Switzerland
Today, we’ve been able to generate our first cloud-free Landsat 8 mosaic for the entire Switzerland for the year 2016. On our single test server it tooks about 4.5h hours of computation (Scene Count: 184; Pixel Count: 139’733’863) to generate the mosaic. Here is the result loaded in the web UI: And here is the final […]
