[FreeGeoCZ] Re: [GRASS-dev] [bug #5396] (grass) hermannskogel datum parameters for Slovakia

["Martin Landa" <landa.martin AT gmail.com>]

Hi all,

after discussion in the CzechoSlovak mailing list I fixed this bug,
there is common geodetic datum for Czech Republic and Slovakia.

hermannskogel "towgs84=570.8,85.7,462.8,4.998,1.587,5.261,3.56" "Czech
Republic/Slovakia" " "

Best, Martin
