As expected the overall error is much bigger and the improvement is not as good as for the upscale 3 model.

Tuning the machine learning hyperparameters with Keras Tuner results in an improved Super-resolution model.

Thanks to Rouven from for the hint.

The deadline for the EU countries for INSPIRE ANNEX 2 was in october 2020. ANNEX 2 includes DEMs. The INSPIRE Data Specification on Elevation–Technical Guidelines defined that the EVRF2007 realization of EVRS should be adopted as height vertical reference for pan-European geo-information. The actual realization of EVRF is 2019. As far as I know Poland is the first country that realized that requirement for there free DTM.
