The worldwide border between Italy and Switzerland & Austria within the Alps largely follows the trail of the watershed line. Sadly on account of international heating and shrinking glaciers the Alpine watershed line retains on shifting. The result’s that the border between Italy and its Alpine neighbors can also be continuously shifting.
In 2016 the Italian Limes challenge tried to trace the motion of the Italy-Austrian border in real-time. With the intention to do that it put in 25 sensors on prime of a glacier at Mt. Similaun. Each two hours these sensors recorded and transmitted their positions. This allowed the shifting border between Italy and Austria to be up to date and mapped in close to real-time.
3D map displaying the place of the Italy-Austria border in 1920 and 2016 and the place of 25 border sensors
The Italian Limes challenge is fantastically illustrated utilizing a 3D map of Mt. Similaun. On prime of this map you may view the Italy-Austrian border in 1920 and the border’s place in 2016. The map additionally exhibits the situation of the 5×5 grid of GPS items which have been used to trace the glacier’s actions in three dimensions in close to real-time.
