20001121: 20001117: dcredbook for redbook graphics in the LDM

Mike,

First, does your LDM process have permission to connect to your X server?
The logs appear to show that the product is read in, bu the gif
is not created. As I mentioned before, the gf driver will require that
an X server be available. (you can create an alternate server with Xvfb
and a screen :1 as an alternative to drawing on your console).

More importantly, NMAP does not view gifs. You can import these
products into NMAP as VGF files however. To create vgf files
from the redbook graphics, you an use "dcredbook" as the
decoder in the script (instead of dcredbook_gf) and use the
gempak VG device, like 'vg|%P-YYYYMMDDHHNN.vgf', making sure to
run gpend within the script since a gplt process will be created.
You do not need an X server to create vgf files.

To import vgf files into NMAP, you can use the pgpalette "Open" option and
Browse for the file in the data directory, or you can use the DATA menu and
select the VGF type. The data directory fore the vgf files for NMAP is specified
in the $GEMTBL/nmap/vgf.nmap file. The "Local" directory is the current working
directory, the other vgf classes have directory names defined in the vgf.nmap 
file.

For clarification, gif format files do not have any georeferencing information.
They are just pictures woth lines etc. VGF files have lats and lons associated 
with
the lines so that they can be edited, remapped, and reprojected.

>but my experience is that the hgardware fonts supplied by the X server look
>much
>better than the software fonts that gif2 will have to use).

>Lastly, you will need the environmental variables GEMMAPS and GEMTBL for
>the mapfiles and tables that define the redbook products respectively.

>You'll see at:
>http://www.unidata.ucar.edu/packages/gempak/tutorial/manual/chap6/chap6.sht
>ml?dcredbook
>that the filename for the output is a GEMPAK DEVICE definition, not just
>a filename. The device, filename, geometry and color options are specified
>just as you would in a GEMPAK program.
>
>In order to specify the environmental variables and X server above, I'd

>piping the output to a script, rather than directly to the decoder (unless

>WMO  ^NOAAPORT\.NWSTG\.GRAPHIC\.P.*
>     PIPE  -close   /npfos/noaaport/nawips/bin/scripts/dcredbook_gf.csh
>
>
>So, dcredbook_gf.csh will be a csh script that the graphics will be piped
>to.
>
>Here is an example of the dcredbook_gf.csh script that works for me.
>You can place it in your scripts directory (or wherever) and use
