• Eva has difficulties with downloading the Functional Map of the World (fMoW) Dataset for Temporal SatMAE. She is using WSL 2, I am using WSL 1.
• I reactivated my AWS account from the MCAS period, but this seems to require IAM credentials, instead of my root account credentials.
• Installing aws-cli via snap doesn't work on WSL 1, so I tried it by downloading the zip.
• That installation method seems to work.
• Tried the command aws s3 ls s3://spacenet-dataset/Hosted-Datasets/fmow/fmow-full/, which fails on missing credentials. Suggested to do aws configure.
• Following the AWS configure instructions.
• I still have two access keys, but the Create access key (requested by aws configure is grey (although both are now active (oldest was inactive, activated and deactivated it again).
• A grey key means that I have used my maximum number of keys, so I have to delete one key and create a new one (secret key is displayed only once).
• Created a new key, which can be used to configure aws (although not recommended use).
• At least I could do aws s3 ls: 2019-08-14 22:23:18 1710 CHANGELOG.md

• The command aws s3 cp s3://spacenet-dataset/Hosted-Datasets/fmow/fmow-full/README.md ./ worked for me.
• The actual challenge run in 2017, this is an archive of the challenge website.
• The challenge indicates that the bucket owner pays for the storage, but the user pays for the download via Requester Pays buckets. No costs are in my account for downloading the README.
• Yet, I didn't use the command --request-payer requester, so this feature seems no longer active.
• The visualizer is java based.
• According to github dataset, access is free.

• For Methane plumes, this ESA presentation from 2022 is interesting.
• Next to Sentinel data, they also pointed to ZY1 and PRISMA data. According to egusphere (2023) both have Targeted coverage, the PRISMA is an Italian satelite (2012?) , data is public. The ZY1 is the Chinese satelite Ziyuan 1, goverment data.
• The egusphere experiment was a controlled release of methane. The code is github, the underlying infrared satellite images not.

• For systems where the dynamics evolve over time, SineNet could be a solution. Architecture is an extension of conventional U-Nets.

• Read WordlCereal article (May 2023). They indicated that Potapov et al (2022) were the first to present time series of global maps, and that they needed intervals of 4y to capture sufficient clear-sky observations.
• The validation of the annual temporary crop maps is impressive, not only that several experts looked at high-resolution satelite and street-view historical data for 5000 sample sites; they also visited the site in person when in doubt.
• The WorldCereal paper is at moment only cited twice:
  • Building a community-based open harmonised reference data repository for global crop mapping (self-citation of Hendrik Boogaard)
  • Investigating the Use of Street-Level Imagery and Deep Learning to Produce In-Situ Crop Type Information (classifies maize, wheat or other, in France).
