Weißer Stein (Eifel) 2007 the University of Liège executed measurements and found a height of 692 m (TAW, Belgian standard). The altitude meter of Google Earth caused some doubt about Signal de Botrange (694 m TAW) as Belgium's highest point because its vertical reference EGM96 deviates a couple of meters from the German Normalnull and the Belgian TAW, thereby suggesting an altitude of 701 m for the Weißer Stein. An accurate control by the Belgian National Geographic Institute in 2010 showed the Weißer Stein to be at maximum 693.3 m TAW (=691 m NN), with which it differs by less than 1 m
