[ldmMcidas #OPC-671989]: ldm-users: Area - GINI Problem... ?

Hi Rodrigo,

I apologize for the slow reply.  I am currently in Burkina Faso (Africa) where

conference activities and slow/non-existent network connections have severely
hindered my ability to respond to emails...

OK, I understand.

GINI imagery is available in two different IDD datastreams: FNEXRAD and
NIMAGE, and the FNEXRAD feed contains some imagery in GINI format, and
some in AREA format.

The pqact.conf action you sent in your first email (to ldm-users)
contained an action for imagery in the UNIWISC (aka MCIDAS) datastream.
It is, therefore, likely that you are not decoding GINI images because:

- you are not requesting the data in your ~ldm/etc/ldmd.conf file
- if you are requesting the data, you do not have decoding actions
  in your ~ldm/etc/pqact.conf file(s)

For reference, ldmd.conf request lines for data in GINI format would
look something like:

request FNEXRAD ".*" idd.unidata.ucar.edu
request NIMAGE  ".*" idd.unidata.ucar.edu

(Just so you know, if you request all of the NIMAGE data, you will receive
a LOT of data every hour.  Also, the imagery in the NIMAGE feed only covers
North America, Puerto Rico, Alaska, and Hawaii.  It does not extend further
south than about 20N latitude, so it will be of little interest for
users in Chile.)

Example pqact.conf actions to process these data would look something like:

No worries.

I am curious about why you want to ingest and serve the NIMAGE images given that
they do not cover any portion of South America.  Is your objective to serve
all of the data possible as a test?

I am travelling back to the US today (it takes a full day), so I will not
be reading email again until Monday.

Cheers,

Tom
