Encoding cross-task relationships between building footprints and heights slashes height estimation error by 7% – more effective than just refining individual encoders.
GeoFormer is an open-source Swin Transformer framework that jointly estimates building height (BH) and foot-print (BF) on a 100 m grid using only Sentinel-1/2 imagery and open DEM data and a geo-blocked splitting strategy ensures strict spatial independence between training and test sets.
