Mapping The H2o Ice Age

The final Ice Age occurred 110,000 to 12,000 years ago. The Last Glacial Maximum (LGM) was the final menses inwards this Ice Age when the H2O ice sheets were at their greatest extension. This was to a greater extent than or less 26,500 years ago.

Thanks to the Swiss federal mapping way y'all tin straightaway persuasion a 2.5D map of how Switzerland looked during the Last Glacial Maximum. You tin persuasion 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 operate past times of the normal Digital Elevation Model used past times the Swiss mapping agency. Therefore the operate past times information is non genuinely right for the Last Glacial Maximum. Ralph has thus created his ain WebGL 2.5D map of Switzerland using the right operate past times information for the Last Glacial Maximum.

You tin persuasion Ralph's map in addition to a seat out of screenshots comparison the differences inwards operate past times information inwards his LGM map amongst that of the Swiss Geoportal at Spatialists.
