Re: 20050519: IDV - Eumetsat CLM GRIB2 file

Markus,

could you tell us about this grid file?  projection 90 is a space view
grid and we aren't quite sure how to handle the projection.  manual states
that this is an orthographic view, is that the same as a orthographic
projection from  the Snyder 1987 reference manual?  also do you have code
to create the projection?

thanks,
robb...
