The final Ice Age occurred 110,000 to 12,000 years ago. The Last Glacial Maximum (LGM) was the final menstruum inwards this Ice Age when the H2O ice sheets were at their greatest extension. This was roughly 26,500 years ago.
Thanks to the Swiss federal mapping means you lot tin instantly sentiment a 2.5D map of how Switzerland looked during the Last Glacial Maximum. You tin sentiment the Swiss LGM map inwards 2.5D, on a WebGL enabled browser, on the Swiss Geoportal.
Ralph Straumann has noticed that the Swiss Geoportal map overlays the LGM layer on overstep of the normal Digital Elevation Model used past times the Swiss mapping agency. Therefore the tiptop information is non genuinely right for the Last Glacial Maximum. Ralph has thence created his ain WebGL 2.5D map of Switzerland using the right tiptop information for the Last Glacial Maximum.
You tin sentiment Ralph's map together with a release of screenshots comparison the differences inwards tiptop information inwards his LGM map amongst that of the Swiss Geoportal at Spatialists.
