Learning from urban form to predict building heights

Map of the three experiments on the test set of Brandenburg.
(A) Experiment 1: No local data are available, and the model is trained only on data from other countries. (B) Experiment 2: Scarce local data are available—we add 2% of the test set to the training set, to test the hypothesis that these data provide relevant data for training the model. (C) Experiment 3: The main city of the area is available—we add this city to the training. The areas in blue are the training set and the area in red is the test set.
