Can you then look at the remapped images using McIDAS-X 7.8 routines like IMGLIST, IMGDISP, IMGPROBE? >However, the software that reads the remapped imagery and operates on it is >the problem. The software uses the following mcidas function prototypes: > extern void readd_ * > extern void araopt_ * > extern void redara_ * > extern void clsara_ > extern int nvset_ > extern int nv1sae_ > extern int opnara_ * These entry points did not change between 7.7 and 7.8. >I see in the release notes that for the above (asteriked) prototypes, the >calls to the subroutine abort have been changed to mcabort.

However, when reading the band data (channels 1-5) I am >not getting any info. Any ideas? What does an IMGLIST show for the remapped image? Does it indicate that the image is multibanded? Also, can IMGDISP display any one of the bands? Perhaps the band information word (1-based word 19) in the AREA file header is not being written out correctly. >I have since recompiled the software to use the old 7.7 library until I can >resolve the problem with 7.7.

I emailed Tom Yoksas yesterday thinking it may be a problem with the modified mcidas function prototypes (e.g., redara_, readd_). Tom noted that these prototypes were upgraded in v7.7 so he asked me to check into the imagery (i.e., can you use IMGDISP, IMGPROBE, IMGLIST on the imagery). I was able to do this but the key here is that the version of remap2.pgm that we use to remap the raw GOES imagery was compiled with mcidas7.6. I recompiled remap2.pgm with mcidas7.7 and mcidas7.8. In both cases, remap2.k runs and creates the correct file size but when viewing the imagery (all bands) all values are 0. So, it now looks like the problem originates when upgrading from v7.6 to v7.7. On a side note, I have a note that we modified remap2.pgm when we upgraded to v7.6 per your instruction to fix the county map navigation problem. Can you compile remap2.pgm and run successfully with v7.7 and v7.8? Thanks for any help you can provide.

Refresh my memory on what that change was. > Can you compile remap2.pgm and run successfully > with v7.7 and v7.8? I can run the XRD version of remap2 just fine on v7.8, so I don't think it's related to any low-level routine. dave > > > Thanks for any help you can provide. > > Mary Ellen > > Mary Ellen Craddock > Meteorologist > Northrop Grumman Information Technology, TASC > 4801 Stonecroft Boulevard > Chantilly, VA 20151 > (703) 633-8300 x4022 > address@hidden
