REFAID_DAEMON

Continually produce reference aids for AVHRR archive images.

Function:

Continually produces reference aids for AVHRR archive images using the REFAID procedure.

Parameters:

PRIORITY
Priority CEOS IDs. List of CEOS IDs that have processing priority. They must be specified from highest priority to lowest. Images acquired by other CEOS IDs will be processed only after reference aids have been produced for images acquired by the priority stations. To specify no priority, set PRIORITY to NULL (--).

Example:

  1. LAS> refaid_daemon priority=(sfl hbt)

    AVHRR archive images in the ADAPSING directory will have reference aids created. First the images from the Sioux Falls, SD (SFL) station, then images from the Hobart, Australia (HBT) station, and then all other images will be processed. After each image is processed, it is moved into the ADAPSARC directory to be archived.

Description/Algorithm:

REFAID_DAEMON continually creates reference aids for AVHRR archive images. It searches the ADAPSING directory and selects images in order of the stations specified in PRIORITY. Images within the same priority group (i.e., from the same CEOS ID) will be processed in alphabetical order of the image name. All reference aids are created (browse image, microfiche image, database record, and facsimile image if indicated in the PRIORIFY;FAX table) before the image is moved to the ADAPSARC directory to be archived.

Nonfatal Error Message:

    None.

Fatal Error Messages:

    None.
