European Vertical Reference System (EVRS)
EVRS is a zero-tidal gravity-related height reference system. The EVRS is realized by the geopotential numbers and normal heights of nodal points of the United European Levelling Network 95/98 (UELN 95/98) extended for Estonia, Latvia, Lithuania and Romania in relation to the Normaal Amsterdams Peil (NAP). The geopotential numbers and normal heights of the nodal points are available for the participating countries under the name UELN 95/98 which is now given the name EVRF2000.

“No European spring had shown him the same intermixture of delicate grace and passionate depravity that marked the Maryland May.”
—Henry Brooks Adams (1838–1918)
“I tell you, hopeless grief is passionless;
That only men incredulous of despair,
Half-taught in anguish, through the midnight air
Beat upward to God’s throne in loud access
Of shrieking and reproach. Full desertness,
In souls as countries, lieth silent-bare
Under the blanching, vertical eye-glare
Of the absolute Heavens.”
—Elizabeth Barrett Browning (1806–1861)
“Meaning is what essence becomes when it is divorced from the object of reference and wedded to the word.”
—Willard Van Orman Quine (b. 1908)
“I candidly confess that I have ever looked on Cuba as the most interesting addition which could ever be made to our system of States. The control which, with Florida, this island would give us over the Gulf of Mexico, and the countries and isthmus bordering on it, as well as all those whose waters flow into it, would fill up the measure of our political well-being.”
—Thomas Jefferson (1743–1826)
