Hi, guys:
When I use the fallowing code:

mp = Obj_New('cgMap', 'Cylindrical Equal Area',Ellipsoid='WGS 84', /GCTP, $
CENTER_LONGITUDE=105, STANDARD_PARALLEL=30)

I get error:

% MAP_PROJ_CHECKPARAMS: Parameter CENTER_LATITUDE not allowed for projection: Cylindrical Equal Area. Allowed
parameters include: CENTER_LONGITUDE, FALSE_EASTING, FALSE_NORTHING, SEMIMAJOR_AXIS,
SEMIMINOR_AXIS, STANDARD_PARALLEL.

So, is that a cgMap error? thanks!

Dave
