[Geotools-gt2-users] different towgs84 definitions for same authority datum code ("Amersfoort")?

[Nikolai F. <nik...@gm...>]

hi,
analysing content of
/modules/plugin/epsg-wkt/src/main/resources/org/geotools/referencing/epsg/wkt/epsg.properties

i came across different towg84 definitions for DATUM "Amersfoort",
epsg:6289.
see attached text file for space formatted comparison.

basically "28992=PROJCS["Amersfoort / RD New""
has differences compared to rest (62896405, 4289, 28991, 7415 and 7408).

would anyone have an idea what is the story behind it?

cheers, niki
