Case study for the Czech Republic.	2017	10	.pdf	application/pdf	3348	207	55	For purposes of this accuracy test, we have focused mainly on aerial photographs from 1938 and 1953 – as these datasets depict the landscape before or right after the start of the heavy industrialization of many regions in the Czech Republic. One of the purposes how to further use the derived Digital Surface Models (DSM) is georelief transfiguration analysis – aerial photographs may serve as a data source for the landscape 3D reconstruction as was presented in Pacina et al.
