Sentinel-3 Toolbox (S3TBX)

A toolbox for the OLCI and SLSTR instruments on board of ESA's Sentinel-3 satellite.

The project page of SNAP, and the sentinel toolboxes can be found at http://step.esa.int. There you can find tutorials, developer guides, a user forum and other interesting things.

Building S3TBX from the source

The following gives a brief introduction how to build the S3TBX. More information can be found in the Developer Guide.

Download and install the required build tools

• Install Java 8 JDK and set JAVA_HOME accordingly. A distribution of OpenJDK is suggested. Several distributions are available, for example
  • Azul Zulu
  • AdoptOpenJDK
  • Amazon Corretto
• Install Maven and set MAVEN_HOME accordingly.
• Install git

Add $JAVA_HOME/bin, $MAVEN_HOME/bin to your PATH.

Clone the S3TBX source code and related repositories into a directory referred to a ${snap} from here on

cd ${snap}
git clone https://github.com/senbox-org/s3tbx.git
git clone https://github.com/senbox-org/snap-desktop.git
git clone https://github.com/senbox-org/snap-engine.git

Build SNAP-Engine:

cd ${snap}/snap-engine
mvn install

Build SNAP-Desktop:

cd ${snap}/snap-desktop
mvn install

Build Sentinel-3 Toolbox:

cd ${snap}/s3tbx
mvn install

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

mvn clean
mvn 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 s3tbx 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 JDK for the main project.

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: --userdir "${snap}/s3tbx/target/userdir" --clusters "${snap}/s3tbx/s3tbx-kit/target/netbeans_clusters/s3tbx" --patches "${snap}/snap-engine/$/target/classes;${snap}/s3tbx/$/target/classes" Working directory: ${snap}/snap-desktop/snap-application/target/snap/ Use classpath of module: snap-main

Enjoy developing!
