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
