Towards the end of 2013, surveyors braved temperatures of -10⁰ C and winds of over 50 km/h, and set up a Leica Viva GS14 GNSS antenna to measure the height and also take roughly 100 point measurements of the ice cap. The Leica MS50 MultiStation scanned the ice cap at an altitude of over 4,800 m under extreme conditions and recorded thousands of points in a matter of minutes.
The 2013 expedition proved that the current elevation of Mont Blanc is 4,810.02 m, which is 42 cm less than in 2011. The actual rock summit has an altitude of 4792 m, however the snow covering the peak may vary the actual summit’s altitude anywhere from 15 to 20 m. Expedition partner Géomédia calculated the volume of the ice cap covering the rocky summit at 20,213 m³ and produced a 3D animation from the scan data as well. In the future, these results will help researchers determine possible changes to the ice cap caused by global warming.
Philippe Borrel, owner of the surveying company Cabinet Borrel and an experienced member of the expedition team said, “Using the Leica Nova MS50 MultiStation to make a 3D model of the biannual Mont Blanc summit expedition was a challenging exercise that resulted in highly accurate data. Collecting data under such extreme conditions quickly and efficiently is extremely important. This time, we were able to reduce time expenditure needed to complete the task. The MultiStation was surprisingly easy to carry in a backpack, considering the rocky terrain, steep slopes and windy ridges we had to climb.”
