9.7 Image Directory Structure for NMAP2 & Garp
Image Directory Structure for NMAP2 and Garp
NMAP2 and Garp provide the capability to view and animate image products
such as satellite and radar products. These programs provide the user with
a user friendly Graphical User Interface (GUI) for viewing these files.
Additionally, both programs have the capability to update the running loop
when new files are added to the image directory structure.
In order for GUIs to identify the various files, the user
must configure their directory structure in a prescribed format,
as the directory names are used within the program.
LDM pattern/actions for Radar and Satellite
imagery are provided as examples for filing data in the heirarchy shown
below.
The environmental variables $SAT
and $RAD
in Gemenviron must be set to the top of the directory tree.
The image directory structure is as follows:
DATA SOURCES DATA SECTORS TYPE IMAGES
$SAT --------- GOES-10 ----- 8km ---------- WV ----- WV_yyyymmdd_hhmm
| |
| 4km---------|- VIS ---- VIS_yyyymmdd_hhmm
| |- IR ----- IR_yyyymmdd_hhmm
|
----- GOES-12 ----- 8km ---------- WV ----- WV_yyyymmdd_hhmm
| |
| 4km---------|- VIS ---- VIS_yyyymmdd_hhmm
| |- IR ----- IR_yyyymmdd_hhmm
|
----- EAST-CONUS -- 1km ---------- VIS ---- VIS_yyyymmdd_hhmm
| | |
| | |
etc. etc. etc.
$RAD ----- NIDS -------- FTG ---------- N0R -- N0R_yyyymmdd_hhmm
| | |- NCR -- NCR_yyyymmdd_hhmm
| | |-
| etc. etc.
|
----- craft ------ KFTG -------- KFTG_yyyymmdd_hhmm
|
|
etc.
The GUIs use the directory names it finds under $SAT and $RAD to create
the menu buttons for the appropriate image selection. Additionally,
the subdirectories allow the user to select the platform or region,
the product and/or band, and finally the image times.
Daunting as the above directory structure may seem, the included
LDM pattern actions provide the method for automating the storage of
these files. By using the auto update feature, the GUIs will
periodically search the directory for new images and update the
animation sequence automatically.
