New dataset and AI model improve building height estimation from satellite imagery

By PulseAugur Editorial · [1 sources] ·

Researchers have introduced the PhiSat-2--Height Dataset (PHDataset) and a novel neural network called TSONet for estimating building heights using monocular imagery. PHDataset comprises 9,475 image pairs from 26 cities globally, paired with open building height references. TSONet utilizes multiscale decoupled height representation and footprint-conditioned height reconstruction to improve accuracy. Evaluations show TSONet reduces root mean square error (RMSE) and mean absolute error (MAE) by 3.64% and 4.49% respectively, outperforming existing methods and demonstrating the value of PhiSat-2's spatial-spectral information for urban mapping.
