The SENTINEL-1 Toolbox

The project page of SNAP and the sentinel toolboxes can be found at http://step.esa.int. There you will find a tutorial about the usage of the application, a forum where you can ask questions and lots of other interesting things.

Building S1TBX from the source

1. Download and install the required build tools

   • Install J2SE 1.8 JDK and set JAVA_HOME accordingly.
   • Install Maven and set MAVEN_HOME accordingly.
   • Install git

2. Add $JAVA_HOME/bin and $MAVEN_HOME/bin to your PATH.

3. Clone the S1TBX source code and related repositories into SNAP/

   git clone https://github.com/senbox-org/s1tbx.git
   git clone https://github.com/senbox-org/snap-desktop.git
   git clone https://github.com/senbox-org/snap-engine.git
   git clone https://github.com/senbox-org/snap-installer.git
   

4. CD into SNAP/snap-engine:

   mvn clean install

5. CD into SNAP/snap-desktop:

   mvn clean install

6. CD into SNAP/s1tbx:

   mvn clean install

7. If unit tests are failing, you can use the following to skip the tests

   mvn clean install -Dmaven.test.skip=true

Setting up IntelliJ IDEA

1. Create an empty project with the SNAP/ directory as project directory

2. Import the pom.xml files of snap-engine, snap-desktop and s1tbx as modules. Ensure not to enable the option 'Create module groups for multi-module Maven projects'. Everything can be default values.

3. Set the used SDK for the main project. A JDK 1.8 or later is needed.

4. Use the following configuration to run SNAP in the IDE:

   • Main class: org.esa.snap.nbexec.Launcher

   • VM parameters: -Dsun.awt.nopixfmt=true -Dsun.java2d.noddraw=true -Dsun.java2d.dpiaware=false All VM parameters are optional

   • Program arguments: --clusters "E:\build\SNAP\s1tbx\s1tbx-kit\target\netbeans_clusters\s1tbx";"E:\build\SNAP\s1tbx\s1tbx-kit\target\netbeans_clusters\rstb" --patches "E:\build\SNAP\snap-engine\$\target\classes";"E:\build\SNAP\s1tbx\$\target\classes";"E:\build\SNAP\s1tbx\rstb\$\target\classes"

   • Working directory: SNAP/snap-desktop/snap-application/target/snap/

   • Use classpath of module: snap-main
