Installation

SNAP

ERS_NRB requires ESA’s Sentinels Application Platform (SNAP) software to produce ERS_NRB products. It has been developed based on SNAP version 8. Downloaders for different operating systems can be obtained from the official webpage.

The following code can be used to replicate the software installation on a Linux OS:

VERSION=8
TARGET=~/SNAP"$VERSION"

INSTALLER=esa-snap_sentinel_unix_"$VERSION"_0.sh
wget https://download.esa.int/step/snap/"$VERSION".0/installers/"$INSTALLER"
bash $INSTALLER -q -dir $TARGET
$TARGET/bin/snap --nosplash --nogui --modules --update-all

See also the web page on how to update SNAP from the command line.

Alternatively, updates for individual modules and versions can be downloaded in the SNAP Update Center. The latest bundle that was used during release of version 0.1.2 is available here: https://step.esa.int/updatecenter/8.0_20220323-143356/.
