[Geotools-gt2-users] EPSG 23700

[Philippe D. <pdu...@gm...>]

i'm working with data in EPSG:23700, and i've noticed big
transformation errors when going from 23700 to 4326.

I've updated the 23700 definition in the epsg.properties file from
gt2-epsg.jar with the following line :

23700=PROJCS["Hungarian_1972_Egyseges_Orszagos_Vetuleti",GEOGCS["GCS_Hungarian_1972",DATUM["D_Hungarian_1972",SPHEROID["GRS_1967",6378160,298.247167427]],PRIMEM["Greenwich",0],UNIT["Degree",0.017453292519943295]],PROJECTION["Hotine_Oblique_Mercator_Azimuth_Center"],PARAMETER["False_Easting",650000],PARAMETER["False_Northing",200000],PARAMETER["Scale_Factor",0.99993],PARAMETER["Azimuth",90],PARAMETER["Longitude_Of_Center",19.048571778],PARAMETER["Latitude_Of_Center",47.14439372222],UNIT["Meter",1]]

which is a defintion i've found online, and it seems correct, at least
empirically.
