Good to hear from you.
I had some minor offsets when using GSHHS and the theoretical values for standard HRIT/LRIT format data.
I spent some time with e-mail exchanges with NOAA until this was resolved. I can't recall the exact details now - let me check....yes, there were some unusual features in sat-to-earth (and likely earth-to-sat) which I had to code separately. I never did get an explanation why using the standard WMO equations wasn't good enough....
I'm using the images as sent over EUMETCast and the match is now excellent.
