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.
