Monocular Building Height Estimation from PhiSat-2 Imagery: Dataset and Method

ArXi:2603.29245v1 Announce Type: new Monocular building height estimation from optical imagery is important for urban morphology characterization but remains challenging due to ambiguous height cues, large inter-city variations in building morphology, and the long-tailed distribution of building heights. PhiSat-2 is a promising open-access data source for this task because of its global coverage, 4.75m spatial resolution, and seven-band spectral observations, yet its potential has not been systematically evaluated.
