Hi,

 

I would like to transform the vertical datum EPSG:5730 to EPSG:5621

 

For more information about the European height reference systems have a look
at: http://www.crs-geo.eu/

 

I used gdaltransform, but the z value is not changing:

 

The CRS is identical EPSG:3035: ETRS89 European Lambert Azimuthal Equal
Area.

 

gdaltransform -s_srs EPSG:3035+5730 -t_srs EPSG:3035+5621 < xxx.xyz >
xxx3.xyz

 

xxx.xyz:

4650012.500 1649987.500 332.763

4650037.500 1649987.500 337.635

4650062.500 1649987.500 342.153

 

testepsg "EPSG:4326+5773" à success in both cases
 
 
Best,
 
Martin
