This package contains examples on how to use spatial database concepts in XXL. It provides examples of some spatial-join-operators as well as examples for indexing and querying spatial data by means of r-trees. Most examples refer to example-datasets contained in the XXL-distribution, but you can test the algorithms with your own datasets.
To run the tests with default data- and parameter-sets the XXL rootpath and outpath have to be set via the -D command line option of Java. To do this automatically, you can use the script xxl inside bin to start the examples.
