Timing and duration

The AI4EO MapYourCity challenge will take place online from 02 April 2024 to 14 July 2024 16:00 CET.

Participants

Participants from all over the world can participate in the challenge, however, please refer to the Prizes section to verify whether you are eligible to receive a prize in your current location. You must be of legal age in your jurisdiction to participate.

Teams

Each participating team is required to appoint a team leader. This team leader will be the main contact point between the organisers and the team.

Any participant may only be competing in and be part of one participating team during the MapYourCity Challenge. Teams are not allowed to create a second or duplicated entity. The AI4EO organising team may request you to delete any duplicate applications or submissions.

Creating and submitting a solution

For the challenge, you have access to the training and test datasets and a range of tools in the form of a Jupyter Notebook (Starter Pack). All usable data is hosted on the EOTDL. No other datasets might be used for the development of your solution. However, pre-trained models are allowed.

Participants are allowed to upload their solutions every 12 hours (to avoid overload and unfair behaviours). The final submission of your solution must be uploaded latest by 14 July 2024 (16 PM CET), and each valid submission must consist of a test .csv file including the added estimated construction time.

The multi-modal deep-learning system must be capable of estimating the construction year of any given building. To render the challenge more complex and challenging, half of the test data does not include the street view pictures.

Challenge evaluation

The scoring of submitted solutions, respectively the code, are performed by the organisers. The final score is exclusively based on a quantitative evaluation based on different samplings of the test data. A public leaderboard lets you see and compare your current points in relation to other teams’ submissions. A private leaderboard will be disclosed at the end of the competition, to be used for the final ranking. Please note that, if the solution turns out to be not reproducible, or if any concerns about its validity arises, the organisers reserve the right to contact the team leader of the corresponding team to resolve such issues. If the issues cannot be resolved, the team will not be eligible to receive prizes.

For more details on the metrics, see the Metrics section on the Data page.

Solution presentation

The winners of the AI4EO MapYourCity Challenge will be announced shortly after closing of the challenge and publicly awarded during the URBIS24 Workshop in September 2024. To offer the winners the chance to present their great solutions and to ensure full transparency of the products, the three winning teams are expected to present their respective solutions in a pitch-style manner of ca. 10 minutes per team with the use of a short pitch-deck (for example in the form of a PowerPoint presentation).
