Re: ldm-users: Area - GINI Problem... ?

Rodrigo,

Your LDM is not requesting the NIMAGE feed from an upstream computer
as shown on the statistics from your computer:
http://www.unidata.ucar.edu/software/idd/rtstats/siteindex.php?depresion.dgf.uchile.cl

You have to receive the NIMAGE feed to be able to process it woth the
pqact entry
I sent. You are enabled to request these products from
idd.unidata.ucar.edu.

The MCIDAS feed products are area files, which are a completely
different format than the GINI data, and there is no ldm-mcidas program
that converts between the formats.

You can use the FILE action as I provided if you request the NIMAGE feed
from
an upstream ldm. The ldmfile.sh you show in your PIPE action below
is a scriopt that essentially just FILES the data and logs its
reception,
but is completely unnecessary. A simple FILE action as I provide is all
you need.
