The talk will start by defining what we mean by lossless and near-lossless compression in the context of a hyperspectral sounder such as IASI. Standard techniques for lossless file compression will be reviewed – including bzip2 and BUFR, both of which are widely used in EUMETCast. Next we will look at imagery compression, including some published studies of compression in the context of hyperspectral imagery from the AVIRIS aircraft sensor.
