BlueDot Observatory

Our mission is to reveal and share hidden values of Earth observation data.

[BlueDot Observatory @BlueDotObs]

The Water Observatory is an Earth-observation-based solution that provides both global historical and current data on water resources condition utilising #Sentinel2 @CopernicusEU open data. The prototype version of dashboard available at https://t.co/USADHIWXiV

@sergioajv1 Interestingly Barragem do Blang is drying up as can be seen here: https://t.co/pr8a0ZzTym, but Barragem do Salto and Barragem da Divisa nearby seem to be full. Do you know why?

[Sentinel Hub @sentinel_hub]

Situation is indeed dire since July as seen on @BlueDotObs

@_mariosmsk_ @sentinel_hub @David_P_Moore @timesofindia @WHO @WMO @NCEOscience @CopernicusEU @ESA_EO @esa @CyprusDams @WorldResources @QGISCyprus Thank you a lot for your help 😊. We'll add Cyprus in the next iteration, sometime in August.

@malikarrahiem We're extremely happy that you find our app useful and appreciate a lot your feedback. It makes our effort worthwhile.

[Sentinel Hub @sentinel_hub]

Chennai Water Crisis can also be observed at @BlueDotObs https://t.co/iOADiI6H5q @washingtonpost @ESA_EO

[Sentinel Hub @sentinel_hub]

Read a blog post on how to help with improvement of @BlueDotObs water detection algorithms and how to use our open-source #ClassificationApp to crowd-source labeling data for your own use-case. https://t.co/manb4O91KD

@ianschuler @sentinel_hub Love this simple this app is to use. Great example of a web mapping app that balances all the other components on the page and doesn't give all the screen real estate to the map.

@davidbrochart @Walid_Moulahoum @CopernicusEU On TODO list. Water bodies from France will be added in the next iteration.

Some #EO magic 🎆 created by @LubejMatic & @DPeressutti around posters about @BlueDotObs & Spatio-Temporal Deep Learning #eolearn... Presented at #LPS19

[Matic Lubej @LubejMatic]

Posters are up and running, if you can't wait to admire them! Poster section under the main stairs, boards 329 & 330 😊

[BlueDot Observatory @BlueDotObs]

The answer is of course: yes, it can be done. But one has to forget about tiles (🤔 What is a #Sentinel2 tile?🤷‍���️), leave heavy lifting and shoveling of peta bytes of data ⛰️ to the experts like @sentinel_hub and only process (download) what needs to be processed (downloaded).

[BlueDot Observatory @BlueDotObs]

It looks like everyone from Earth observation and remote sensing community is in Milan for ESA's #LPS19 and so are we! Meet us on Thursday at Deep Learning in RS Poster Session: https://t.co/D23vNKKEHg. For those who can't make it ➡️ here's the poster.

[BlueDot Observatory @BlueDotObs]

Is it possible to run global EO value added service at shoestring budget?

BlueDot's challenge:
🔵 Process 10.000 water bodies spread over 90 countries (🇸🇮🇮🇹🇿🇦🇦🇺🇺🇸...) and 3100 #Sentinel2 tiles every 5-10 days since mid 2015, which accumulates to over 2 million observations!

[BlueDot Observatory @BlueDotObs]

@JDoaim Indeed. Thank you for reporting this. The algorithm clearly underestimates the current water extent for this dam. It's suspected that this is due to the Digital Elevation Model data used by the algorithm. We need to investigate this further.

[BlueDot Observatory @BlueDotObs]

@JDoaim @sentinel_hub The surface of Zayandeh Rud Dam has increased for more than 10% in just 5 days. The discharge of water on Karoon Dam has on the other hand helped to stop the rise of its water levels.

@JDoaim @sentinel_hub We hope that emergency discharges will be successful and the catastrophe avoided.
