EVRS2000 and other vertical reference systems

Hello

does anyone has any infos about the vertical reference system EVRS
2000? Is this reference system based on the Amsterdam Ordnance Datum
(Normaal Amsterdams Peil)? What is the difference between EGM96 and
EVRS 2000?

How much is the height difference between Amsterdam height and Metres
above Adria (especially in the area of Austria)?

Kind regards,
Norbert

Hello,

I think your first place to look is here: http://www.euref-iag.net/

EGM96: http://cddis.nasa.gov/926/egm96/egm96.html

You have to be careful, but wikipedia is often good to find references
to more authoritative documents or websites.

Does anyone know how to get a grid file consisting of "geoid
undulations" (it's not the right term) as height differences between
EVRS 2000 geoid model and WGS 84 ellipsoid?

Thank you,
Norbert
