[McIDAS #FDU-863429]: BOWTIE and others

Hi Tyn,

re: SATANGLES
> Does this only work in "probe mode", or can one output to IMAGE too?

I had to read the source code for satangles.pgm for this one:  the program
is setup to read the cursor location and then use the navigation associated
with the displayed image.

I don't know.  After reading the paragraphs on MODIS data in HDF files in
the DSSERVE entry in the Users Guide, I assume that McIDAS does not support
these images.  I do not know this as a fact, however.

Yes, but the ADDE servers are pretty hardwired for certain types of MODIS
HDF data.

I will try.

OK.  I just added it to my distribution and got it to build.  I have not run
any tests, so this will be one of those 'use at your own risk' commands.

> How can i best compile this?

Two routines are needed:

- imgbowtie.c
- gennavblk.for (available on the SSEC FTP server in pub/mug as gennavblk.fr)

The modifications needed in /home/mcidas/mcidas2007/src/makefile are:

1) add building of gennavblk.o to libmcidas:

######################################################################
#-------
# Unidata Fortran sources for libmcidas.
#-------

UPCLIBMcIDAS_FSRCS  = \
                        dfit.for        \
                        fliprte.for     \
                        gennavblk.for   \
                        j1compas.for    \
                        j1xsymb.for     \
                        u0drwmap.for    \
                        u0eraseg.for    \
                        u0frtime.for    \
                        u0newcol.for    \
                        gammln.for      \
                        invlow.for      \
                        newcolor.for    \
                        parserange.for  \
                        putbar.for      \
                        scatter.for     \
                        slong.for       \
                        stats.for       \
                        symplt.for      \
                        tlow2d.for

2) add the appropriate entries in the XRD section for building IMGBOWTIE:

#-------
# Unidata McIDAS-XRD/MDF apps
#-------

 ...

UPCXrdC_Srcs            = \
                        imgbowtie.c     \
                        swnd2cdf.c

 ...

imgbowtie.k             : imgbowtie.o $(NCDFLIBDEPS)
                        @$(L) -o $@ imgbowtie.o $(NCDFLIBARGS)
swnd2cdf.k              : swnd2cdf.o $(NCDFLIBDEPS)
                        @$(L) -o $@ swnd2cdf.o $(NCDFLIBARGS)

Then build the executable and help file:

<as 'mcidas' (assumes McIDAS is already built and that you have FTPed 
imgbowtie.c
             and gennavblk.for to ~mcidas/mcidas2007/src)>
cd ~mcidas/mcidas2007/src
make imgbowtie.k imgbowtie.hlp
ln imgbowtie.k ~/bin
ln imgbowtie.hlp ~/help

Cheers,

Tom
