UNICEF Innovation Office is in charge to map every school in Kenya, Rwanda, Sierra Leone, Niger, Honduras, Ghana, Kazakhstan, and Uzbekistan, applying scalable machine learning over high-resolution satellite imagery, with the aim of accelerating connectivity, online learning and other initiatives for children and their communities and driving economic stimulus under UNICEF's GIGA mission, particularly in low-income countries.

Development Seed's Data team support this project on the training data creation and the ML inference validation.
Training data creation
Development Seed's Data team generated a high-quality training dataset, for machine learning models, using as data sources; schools provided by UNICEF and schools data from OpenStreetMap from 9 countries, which were: Rwanda, Sierra Leone, Niger, Chad, Sudan, Mali, Honduras, Kazakhstan, and Kenya.
Finally, the Data team validated around 120k schools points, adding one of these tags: "dc_has_pattern_school=yes", "dc_has_pattern_school=unrecognized", "dc_has_pattern_school=no"; according the school patterns recognized in each of them.
Post inference validation
Development Seed's Data team performed a validation of the ML inferences from 8 countries (Kazakhstan, Kenya, Rwanda, Niger, Honduras, Uzbekistan, Sierra Leone, and Ghana), validating more than 113k schools tiles.
