New: the coal beneath the Ruhr and the Saar. Two new layers show where the coal seams run. More than 23,000 lines are now on the map, together with the height of the Carboniferous surface: in the south it reaches up to 300 metres above sea level, in the north it lies 840 metres below, buried under younger rock. One thing worth knowing: the seams are drawn at the top of the Carboniferous, not at the ground surface. North of the Ruhr that surface lies hundreds of metres deep. The maps were compiled between 1949 and 1954 by the Geological Survey of North Rhine-Westphalia and the Saarland environmental agency. Visitor mines are now marked as such, with a note that you may only enter them on a guided tour. The layer list has been tidied up. Layers are grouped, and each one explains where its data comes from, how old it is and what it does not show. orecast now also starts in German on a German device. You can switch the language in your account.
