Open Cities AI Challenge: Segmenting Buildings for Disaster Resilience Hosted By The Global Facility for Disaster Reduction and Recovery
Can you map building footprints from drone imagery? This semantic segmentation challenge leverages computer vision and data from OpenStreetMap to support disaster risk management efforts in cities across Africa.
As urban populations grow, more people are exposed to the benefits and hazards of city life. One challenge for cities is managing the risk of disasters in a constantly changing built environment. Buildings, roads, and critical infrastructure need to be mapped frequently, accurately, and in enough detail to represent assets important to every community. Knowing where and how assets are vulnerable to damage or disruption by natural hazards is key to disaster risk management (DRM).
The Global Facility for Disaster Reduction and Recovery (GFDRR) is a global partnership that provides knowledge, funding, and technical assistance towards achieving the vision of a world where resilient societies manage and adapt to ever-changing disaster and climate risk, and where the human and economic impact of disasters is reduced. Recognizing the significant potential of machine learning and geospatial technologies for DRM, GFDRR Labs is engaging the expert community through initiatives like this challenge to advance the creation of global public goods for improving disaster resilience.
The goal of this challenge is to accelerate the development of more accurate, relevant, and usable open-source AI models to support mapping for disaster risk management in African cities.
Better performing and responsibly used AI systems can provide more accurate, faster, and lower-cost approaches to assessing risk and protecting lives and property.
There are 2 competition tracks:
- Semantic Segmentation track: Build models to identify building footprints from aerial imagery across diverse African cities.
- Responsible AI track: Apply an ethical lens to the design and use of AI systems for DRM. Segmentation track participants must also submit at least once to the Responsible AI track to qualify for the $12,000 in cash prizes.

Selection of winners
This Competition is a challenge of skill and the final results are determined by evaluating a combination of quantitative and qualitative factors, as more fully described on the Competition Website. For that portion of the Competition evaluated quantitatively, the results will be determined solely by leaderboard ranking on the private leaderboard based on an objective statistical evaluation metric published on the Competition Website prior to commencement of the Competition (subject to compliance with these Competition Rules). Participants' scores and ranks on the Competition Website at any given stage of the Competition will be based on the objective statistical evaluation metric described on the Competition Website, as determined by applying the predictions in the Submission to the ground truth of a validation dataset whose instances were a fixed set sampled from the Data. For that portion of the Competition evaluated qualitatively, the results will be determined by a panel of judges, as more fully described on the Competition Website. As more fully described on the Competition Website, the Competition may have a quantitative winner, a qualitative winner, a combined quantitative and qualitative winner, or all three.
The evaluation metric used for scoring and ranking Submissions will be displayed on the Competition Website.
Any prize awards are subject to verification of eligibility and compliance with these Competition Rules. All decisions of DrivenData, the Competition Sponsor and/or judges will be final and binding on all matters relating to this Competition. DrivenData reserves the right to examine the Submission and any associated code or documentation for compliance with these Competition Rules. In the event that the Submission demonstrates a breach of these Competition Rules, Competition Sponsor or DrivenData may at its discretion take either of the following actions:
- disqualify your Submission(s); or
- require that you remediate within one week all issues identified in your Submission(s) (including, without limitation, the resolution of license conflicts, the fulfillment of all obligations required by software licenses, and the removal of any software that violates the software restrictions).
A tie between two or more valid and identically ranked submissions will be resolved in favor of the tied submission that was submitted first.
A Participant may decline to be nominated as a Winner by notifying DrivenData directly within one week following the Competition deadline, in which case the declining Participant forgoes any prize or other features associated with winning the Competition. DrivenData reserves the right to disqualify a Participant who so declines at DrivenData's sole discretion if DrivenData deems disqualification appropriate.
Prizes and conditions
If the Competition has a prize, the Prize Winner(s) will be notified and announced within 30 days of the end of the Competition on the Competition Website.
The Prize Winner(s) will receive their prizes awarded as a check or electronic transfer from DrivenData.
If a Team wins a prize, all Team members must submit a single written statement describing how the prize is to be allocated among the Team members. If the Team fails to submit such statement within 30 days after DrivenData requests it, then DrivenData will distribute the prize among Team members in equal shares and will have no further obligation to winning Team members.
As a condition of receipt of the prize, winner must deliver the algorithm's code and documentation to DrivenData. The source code must contain a description of resources required to build and run the algorithm. The accompanying documentation should be consistent with DrivenData's Winning Model Documentation Template, which will be provided to winners within 30 days of the end of the Competition Period.
The prize may be awarded to an alternate winner if required documentation is not returned within thirty (30) days after mailing to winner, if prize notification letter/email or prize is returned as undeliverable, if winner does not respond to an email or other communication from DrivenData within ten (10) days of the date sent, or if the winner, in DrivenData’s judgment, does not respond to reasonable requests for information related to prize delivery or otherwise unable or unwilling to coordinate prize delivery within thirty (30) days after prize notification. Allow thirty (30) days for prize delivery. By accepting any prize/award, Winner agrees to allow DrivenData and/or the Competition Sponsor to disclose Winner’s first name, first initial of last name, and city of residence, as well as prize information to the extent required by law, and if so required by law, Winner agrees to the disclosure of additional personal information, all without additional compensation.
