Operation method remarks
BeTA2007 is using transformation method NTv2 - National 
Transformation Version 2, this method based on 
interpolation of known shift values of a regular grid, 
values of this grid were computed in advance from networks 
of identical points; 
BeTA2007 contains implict the conversion (change of 
coordinate system) from DE_DHDN / GK_3 to DE_DHDN / Lat-Lon 
and after transformation with method NTv2 (change of datum) 
to ETRS89 / Lat-Lon  the conversion to ETRS89 / UTM
