The map was generated as part of the GARAH 3D basin model. A detailed description of the model parameters and method can be found in the project deliverable D2.4 (https://egdi.geology.cz/record/basic/60f87f43-5ba8-41b3-aaea-0cba0a010833). It was exported from the GARAH Petromod 3D model with the overlay export function in ascii grid format. The export parameters were set to The TR (all) overlay, “average of surface” of the Upper Jurassic at present-day. The coordinate system of the model was set to UTM31 ED50.
