Installation

SNAP

S1_NRB requires ESA’s Sentinels Application Platform (SNAP) software for SAR data processing. Version 1.0.0 has been developed based on SNAP 8. SNAP 9 is supported since version 1.0.2. 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=9
TARGET=~/SNAP"$VERSION"

INSTALLER=esa-snap_sentinel_unix_"$VERSION"_0_0.sh
wget https://download.esa.int/step/snap/"$VERSION".0/installers/"$INSTALLER"
bash $INSTALLER -q -dir $TARGET
$TARGET/bin/snap --nosplash --nogui --modules --update-all

# add SNAP location to the PATH environment variable in the .bashrc file
echo PATH=$PATH:$TARGET/snap/bin >> ~/.bashrc

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 1.0.0 is available here: https://step.esa.int/updatecenter/8.0_20220323-143356/.
