In December 2019, we publicly launched Radiant MLHub, the first open-access cloud-based repository for geospatial training datasets. Since then, we have continuously published new datasets and expanded the ecosystem around Radiant MLHub.
The idea of Radiant MLHub was born in Spring 2018 after several discussions and feedback from members of the community and funders. We had started a new project to develop a global and geographically diverse land cover training dataset using human verification called LandCoverNet. Soon after the launch of LandCoverNet in 2018, we identified a gap in the ecosystem to facilitate publication and uptake of training datasets in our community. That gap in the data value chain led us to the design and implementation of Radiant MLHub.
