  Aerial or satellite imagery is a great source for land surface analysis,
which might yield land use maps or elevation models. In this investigation, we
present a neural network framework for learning semantics and local height
together. We show how this joint multi-task learning benefits to each task on
the large dataset of the 2018 Data Fusion Contest. Moreover, our framework also
yields an uncertainty map which allows assessing the prediction of the model.
