    4 Both APLCorr and Azgcorr are programs that allow geocorrection of ARSF spectral imagery. Azgcorr is produced by Azimuth Systems, and was used for correction of ARSF imagery prior to the 2011 flying season. APLCorr was written in-house at ARSF-DAN, and is used for correction of ARSF imagery from 2011 onwards.

    6 If your data were collected in 2011 or later, you will need to use APLCorr to geocorrect them. If your data were collected in 2010 or earlier, you will need to use azgcorr.
     5Both `aplcorr` and `azgcorr` are programs that allow geocorrection of NERC-ARF hyperspectral imagery.  `azgcorr` is produced by Azimuth Systems, and was used for correction of NERC-ARF imagery prior to the 2011 flying season, `aplcorr` is part of the Airborne Processing Library (APL) written in-house at NERC-ARF-DAN and has been used for data processing from 2011 onwards.

     7Most hyperspectral flights from 2008 onwards have been reprocessed to support APL, please contact us if these data aren't available within the archive at NEODC.

     9For data flown prior to 2008, NERC no longer have a license for `azgcorr` so if you need to geocorrect these data you will have to 1) purchase an individual licence from Azimuth Systems or 2) request to have the data reprocessed by NERC-ARF-DAN.
