Short summary
Millions of aerial photographs represent an enormous resource for geoscientists. In this study, we used freely available historical stereo images covering Switzerland (1979–2006) to derive four countrywide digital elevation models (DSMs) at a 1 m spatial resolution. Our DSMs achieved sub-metric accuracy compared to reference data and high image matching completeness, demonstrating the feasibility of capturing surface change at a high spatial resolution over different land cover classes.
