Image calibration in python

[Marty Landsfeld]

Hello,

I am new to this group and to get started I would like to calibrate some Landsat images with the landsat2RadianceMultiAdd function. I am not sure how to set the bandDefnSeq parameter though. I see that it is suggested to use ARCSI but it doesn't look there is this same functionality in the ARCSI package. Is there any documentation on the format of the rsgislib.imagecalibration.CmdsLandsatRadianceGainsOffsets objects that define this input?

Thanks,

Hi Marty,

The function is just converting from DN to radiance, you can do this using ARCSI. For example:

arcsi.py -s ls8 -f KEA --stats -p RAD -o ./OutputImages \

  -i LC80430342013291LGN00/LC80430342013291LGN00_MTL.txt

For more details see this post: https://spectraldifferences.wordpress.com/2014/05/27/arcsi/

An example of where the RSGISLib function is called within ARCSI is:

Thanks,

Dan
