I´m working currently through the QGIS training manual. However, the data for the spatial analysis exercise in chapter 9.4 (http://docs.qgis.org/2.2/en/docs/training_manual/complete_analysis/analysis_exercise.html) is not available under the link provided (can´t find the archive "exercise_data/more_analysis").
Somebody has the data at hand or can tell me where to download the archive.
