Resource: calibration
| Resource | calibration |
|---|---|
| Overview | Specifies the mapping from image index to value |
| Command Line | -ca=calibration |
| Environment Variable | wxpcalib |
| Possible Values | calibration name (see below) or A,B,C for curve |
| Default Value | none |
Some image types (IR images) have a mapping between image index (0-255) and a value of some nature. For example IR images the mapping is to a temperature value. Some of these are predefined in WXP. For example GINI IR images. But for others, there is no calibration. This resource provides a way to set the calibration mapping.
Possible values for calibration are:
- goesi - GOES I IR calibration
- goes7 - GOES 7 IR calibration
- mtsat - MTSAT IR calibration
- mete - Meteosat Europe IR calibration
- meti - Meteosat India IR calibration
- A,B,C - Logarithmic calibration: T(I) = (A/log( 1+(b/(I+C))))
