Automate building age detection and map your city's history

Hi everyone, Thank you to the organizers for a wonderful challenge. I was able to make submission using overhead high resolution imagery only i.e. using only one mode out of 3 available because of resource constraints. However I am interested in understanding the Sentinel images better.
1. It's mentioned these are 520x520 pixels covering 520x520m but the images are 64x64 pixels. Can you please clarify?
2. Also what is the sequence of bands in the Sentinel 2 imagery specifically the RGB bands.

Thanks once again

Hi,
I try to submit but got error like 
```
request to https://api.ai4eo.eu/score/map_your_city?submission=wFlzOqWRTJm7Mjk9GmCQ failed, reason: getaddrinfo ENOTFOUND api.ai4eo.eu
```
Is it just the problem on my end or indeed the evaluation server not working?

Evaluation Server Down?

Hello, as part of our joint effort with the Earth Observation Training Data Lab innitative (https://www.eotdl.com/) we are offering  cloud workspaces for the participants of this challenge. 

The workspaces can be started automatically by visiting https://hub.api.eotdl.com/. If you don't have an EOTDL account, we encourage you to create one. By default, only CPU cloud machines are available. However, we have a limited amount of GPU-powered workspaces that you can claim for this challenge.

You can get the challenge data directly in the workspace (no need to download) and train your models in the cloud.

In order to request a GPU workspace, please join the EOTDL discord server (https://discord.gg/hYxc5AJB92) and share your team name in the #ai4eo channel. Your team will be added to the waiting list and notified when the workspace is available. 

We hope this feature improves your experience during the challenge ! Let us know if we can support you in any way.



Cloud workspaces available soon!

In the rules page it says "Each valid submission must consist of a test .csv file including the added estimated construction time", which I don't think is clear enough.

I picked the test-set.csv file and created a file with a new column called "label" with my predictions, each an int from 0 to 6. I made it just as the train-test.csv.

When I upload it, a message appears saying "['label'] not in index". What can I do? I'd like to add that it would be nice to have a sample submission file.

How to make a submission?

This is the official topic for those who are looking for a team to join the challenge.

When you decide to join a team, the team leader is notified and can decide either to accept you or not. This mechanism works well when team members already know each other, but it can be difficult to assess an unknown candidate worthiness.

To that end, you can use this thread to promote yourself and share some of your work so team leaders can make their decision and contact you.
