• {@link org.esa.beam.examples.data_export}: very simple examples showing how to read data from a product and write them out: The package conatins three source files:
  • BandWriterMain.java
  • BitmaskWriterMain.java
  • TiePointGridWriterMain.java
• {@link org.esa.beam.examples.ndvi_simple}: a very simple NDVI (normalized differential vegetation index) processor. The package contains a single source file:
  • NdviSimpleMain.java
• {@link org.esa.beam.examples.ndvi_processor}: a more advanced NDVI processor which uses parts of the BEAM processing framework. The example comprises two source files:
  • NdviProcessorMain.java
  • NdviProcessor.java
  • a NDVI processing request file

You can also download the bundled examples as a single ZIP file. In order to compile the examples, the ZIP file also contains a build.xml file for use with the open source tool ant (a kind of make for Java) developed by the Apache Software Foundation.

Newcomers who want to develop export tools and data processors are invited to look at {@link org.esa.beam.examples.data_export} and {@link org.esa.beam.examples.ndvi_simple} first. The first package contains basic tools which lets you extract geophysical data from products. The {@link org.esa.beam.examples.ndvi_simple} package contains a few lines of code showing you how to compute the NDVI value from a MERIS Level 1b input product.

Once you are familiar with the basic concepts, please examine the {@link org.esa.beam.examples.ndvi_processor} example contained in this package. {@link org.esa.beam.examples.ndvi_processor.NdviProcessorMain} implements is a fully functional data processor which uses some important concepts and mechanisms of the BEAM processing framework. Don't be afraid, it is still very easy code. It can be used as a template for your own data processors.

This is the list of the most important API packages used by the examples:

1. The org.esa.beam.framework.datamodel package.
2. The org.esa.beam.framework.dataio package.
3. The org.esa.beam.util package.
