Meters above the Adriatic Sea
Meters above the Adriatic is an indication of the height above sea level with three possible reference heights. In Austria , for example, the information is based on an average water level in the Adriatic Sea at the Molo Sartorio in Trieste ( Trieste level in 1875 ). In the Yugoslav successor states, on the other hand, the system refers to the mean water level at Molo Sartorio from 1900 ( Trieste 1900 gauge ), while an identical height definition for Albania is based on the Durrës gauge , the mean water level in the city of Durrës .
It is abbreviated differently depending on the national language :
- Austria: m above sea level Adriatic Sea , m above sea level A. or müa , colloquially well above sea level , Adria height or functional height
- Hungary : mAf from méter Adria felett
- Yugoslav successor states: mi J. von Metara iznad Jadrana
Height differences between Austria and its neighboring countries
In Austria the normal orthometric height (spheroidal height) is used. Austria's neighboring countries use different reference heights and methods, which leads to differences between the height information. These amount to at the state borders
- Germany: +25 to +34.6 cm (normal height - Wallenhorst - normal height zero )
- Italy: −0.5 to −3.2 cm ( orthometric height - Genoa level )
- Switzerland: −1.6 to −7.5 cm (orthometric height - level Marseille - meters above sea level )
- Slovakia: +57 cm normal height (metrov nad morom (m nm) - Kronstadt gauge )
- Slovenia : −8 to −12 cm (normal orthometric height - level Trieste 1900)
- Czech Republic : +46 to +56.3 cm (normal height - Kronstadt gauge)
- Hungary: +49.6 to +60.6 cm (normal height, Hungarian Tengerszint feletti magasság - Kronstadt gauge).
