It appears that you (and I) are using an older epsg file that has =
several errors in the Austrian projections. I just checked the current =
(version 4.4.7) PROJ epsg file and it has been changed to correct the =
error you found and several other errors (the epsg code for the Austrian =
Lambert, for example, is 31287, not 31297). I compared the 4.4.7 PROJ =
file against the current (version 6.3) EPSG database and all the =
Austrian projections seem OK.
=20
You can download the current version of PROJ from =
http://www.remotesensing.org/proj to get the corrected epsg file.

hi ed,
=20
i got a good hint: lat_0 and lon_0 have to be swaped. now it works.
the problem is that i used EPSG projection and copied the projection =
parameters from the EPSG projection but it is wrong too.
for EPSG 31297 the lat_0 and lon_0 have to be changed.
=20
regards.
