about building heights

[ylxbyy]

Thank you for sharing the building data.

May I ask whether you could explain more about the method used to obtain building heights? e.g. the structure of the model, the training stratage and training data. In addition, how about the accuracy of the building heights?

For some countries, the building footprint data are without height data. Will you release the building height data for those countries in near future?
