>From: Dave Santek <address@hidden> >Organization: Space Science & Engineering Center >Keywords: 200203121732.g2CHWQa09247 McIDAS-X -XCD gribdec.k Dave, >Can you explain how the your gribdec.tar.Z is related to -XCD? Chad put together the original gribdec.tar.Z as a set of the XCD routines and header files that were needed for folks to be able to build the standalone grib decoder, gribdec.k, without having to have -XCD installed. >How does your gribdec.tar.Z differ from the old version we have? Yes. I have updated three XCD C routines; changed the grib.h and gridparm.inc include files, and fixed problems in at least one of the gbtbpds001.* tables and added another. >And, what is meant by: > >"As part of my getting new stuff out, I will be updating the CVS repository >at SSEC with my modifications. Hopefully, they will make it into the >May upgrade from SSEC." > >Is this the new nav module? Or, is there more? The update will be the fixes to the gbtbpds001.* tables, the grid.h and gridparm.inc include files, and the source code modifications in btab.c, Mcgribdecoder.c, Mcmkmcgrid.c, and in gribdec.pgm that is bundled with gribdec.tar.Z. The new gribdec.tar.Z bundle I have put together has all of these fixes and it uses the btab.c routine to create navigation blocks for grib messages with nav type 255.

Brian, I am confused if you are talking about a separate piece of code or -XCD changes. Needless to say the deadline for new code to make it into the upgrade has pasted so I cannot guarantee this will make it, especially since we really have no idea what this is about. Dave will contact TomY for more details. Dee "Hoeth, Brian" wrote: > Thanks, as always, for your very detailed email Tom.
