PRDUTIL LIST dataset
Use PRDUTIL to list, add, and delete calibration block segments for a 1-byte PRD image (e.g., an image created with GRDIMG, IMGFILT or IMGOPER commands). Up to 12 segments can be defined using PRDUTIL. Multiple segments can be used to define a single product (type). For example, segments 2 through 6 can define the product values, corresponding brightness values, product units, scale factors and missing value codes for a product named RH while segment 7 can define the settings for a product named MIX.
PRDUTIL LIST LOCAL/AREA.4205
This entry lists the calibration block segments for the image in position 4205 in the dataset LOCAL/AREA.
PRDUTIL DEL LOCAL/AREA.2 1 RH
This entry deletes calibration block segment number 1 from the image in position 2 in the dataset LOCAL/AREA. The segment type must be RH; otherwise, the segment is not deleted.
PRDUTIL ADD A/A.4205 6 RH 0 100 0 255 %
This entry adds or changes (if previously defined) calibration segment number 6 for the image in position 4205 in the dataset A/A. The product value is named RH with units %, and has a range of 0 through 100 that maps to image brightness values 0 through 255.
PRDUTIL ADD LOCAL/RAIN.20 1 PCP 0 200 194 255 IN 100
This entry adds or changes (if previously defined) calibration segment number 1 for the image in position 20 in the dataset LOCAL/RAIN. The product value is named PCP with units IN, and has a range of 0 through 200 that maps to image brightness values 194 through 255. The scale value of 100 means that the product values will be divided by 100 when accessed by another application, such as IMGPROBE.
