IMGPARM

Creates a multi-band image of parameters useful for composites.

Format

IMGPARM sdataset ddataset [keywords]

Parameters

sdataset	source ADDE dataset name and position; specify one of the following formats:
		group/descriptor.position alias.position
	a position greater than zero represents an absolute position in the dataset; a position less than or equal to zero represents a relative position in the dataset based on image time; for example, 0 is the most recent and -1 is the next most recent; to use default position, do not specify .position (no default for group/descriptor or alias; default=0 for position)
ddataset	destination ADDE dataset name and absolute position; specify one of the following formats:
		group/descriptor.position alias.position
	use only positive integers for position

Keywords

BANd=	source image band (default=1)
BASe=	date time		base date and time used to determine the number of minutes stored in the destination image (default=start date and time of the source image)

Remarks

IMGPARM creates a multi-banded 2 byte image containing several parameters that are useful for creating composites with scientific value. The source image must include documentation.

The contents of each band in the output image are listed below.

Band Number	Content
1	Brightness values
2	Time difference from specified BASE values (seconds)
3	Distance from satellite subpoint (km)
4	Pixel area (km*km)
5	Satellite Sensor number (SS)
6	Wavelength
7	Parallax distance (km*10)
8	Parallax direction (degrees)

Data from polar satellites must contain the entire swath width and be in a local dataset containing Area-format files.

Examples

IMGPARM EASTL/CONUS.-1 MY/AREAS.10 BAND=4

This entry reads in data from the second most recent image in dataset EASTL/CONUS and writes it to a new multi-band image in position 10 of dataset MY/AREAS. The contents of each band are described in the Remarks section above.

IMGPARM EASTL/FD.-1 MY/AREAS.10 BAND=4 BASE=X 15:00

This entry is the same as the previous example, except it uses a base time of 15:00 UTC (rather than the time of the source image) to determine the values for Band 2 (time difference from specified BASE values in seconds).

IMGPARM EASTL/FD.-1 MY/AREAS.10 BAND=4 BASE=#Y 00:00

This entry is the same as the previous example, except it uses the current day (string #Y) and 00:00 UTC (rather than the date and time of the source image) as its base date and time to determine the values for Band 2 (time difference from specified BASE values in seconds).
