Image from the classification lesson Tutorials, lessons and training modules

The Bilko software is supported by lessons that teach image analysis and interpretation. The lessons are designed for students and teachers working on their own with limited support, and come complete with background information, images, palettes, formulae and other tools needed to complete the work.

Bilko aims to promote active learning. Step-by-step instructions for hands-on activities are followed by questions to test student understanding. All questions are provided with model answers that explain the reasoning behind the interpretation suggested.

Tutorials and lessons are available either in PDF format or as 'web pages' (HTML format) that may be downloaded and used off-line with a suitable web browser. There are four broad categories:
