What parameters are giving you difficulty? The constuctor signature is:
public LambertConformalConic( RealTupleType reference, //- earth Reference
double r_major, //- semimajor axis
double r_minor, //- semiminor axis
double s_lat1, //- 1st
standard latitude
double s_lat2, //- 2nd
standard latitude
double lon_center, //-
longitude of grid origin
double lat_center, //- latitude
of grid origin
double false_easting, //- x offset
double false_northing //- y offset
)
Depending on how you want to describe your projection, you might also
want to look at the class:
visad.jmet.GRIBCoordinateSystem which contains some "short-cuts" for
some of the more common
GRIB coordinate systems.
Best regards,
tom
