20040318: HDF2AREA - HDF to AREA conversion (cont.)



Hi Jerry,

Yes. I can send the software to you. It was originally developed to
convert Seaspace TDF imagery to Mcidas area by converting TDF files to HDF
and then Mcidas AREA. I'm currently rewriting the software package, but I
could send you an earlier version. The source code is not well commented
and there several issues regarding proper calibration and navigation of
the GOES imagery. The software currently requires GOES navigation files
which I order from SSEC and uses lookup tables to recover the original
instrument counts. It isn't stand alone either. It needs a working Mcidas
and HDF4 installation. I'm curious if the existing package on Mcidas that
Tom mentioned might be a better option, but I don't know too much about
the EOSDIS HDF format. I suspect it includes a lat/lon mesh field. May
software does not requires that the HDF files contain a lat/lon mesh , however 
the
navigation and calibration of the resulting imagery is very close but does
not exactly match the original GVAR.

Hi Darren,

Thank you very much for your response, it would be great if you could
send me an earlier version of the code. i will try it first and be aware of
the potential problem you mentioned.

Jerry,

Sorry for the late reply. I'm currently writing some documentation about
how to compile the software and run the software, where to place the
navigation files, etc.
I should be finished by early next week if not sooner.
