e shown how new <strong>in</strong>formation can be created from exist<strong>in</strong>g imagery. Neverthelessdetailed preparation of the imagery and software is necessary. The different work<strong>in</strong>gsteps have to be carefully expla<strong>in</strong>ed and illustrated.This case is on a quite advanced level of study, but parts of it could be used toillustrate how remote sens<strong>in</strong>g scientists work. For example, students can digitisean image such as the vegetation on the Corona image. This way they learn how todigitise and how to <strong>in</strong>terpret a satellite image or students can make a multi-temporalcolour composite us<strong>in</strong>g given b<strong>in</strong>ary images. In this way students learn actively howto work with the colour cube, the software and the <strong>in</strong>terpretation of the result<strong>in</strong>gimage. Many other parts of the study can also serve as an example.Conclusion<strong>Education</strong> <strong>in</strong> remote sens<strong>in</strong>g is becom<strong>in</strong>g gradually more important, s<strong>in</strong>ce it is awidely used science with lots of applications. Therefore geography education shouldteach students the elementary use of remote sens<strong>in</strong>g. As <strong>in</strong> many other subjects, therelevance of the study object has to be shown <strong>in</strong> order to motivate students for thematter. Examples, based on realistic cases and exercises, are one of the most efficientways to draw students’ s<strong>in</strong>cere attention. Therefore an example of how to work withremote sens<strong>in</strong>g imagery and software was written out <strong>in</strong> this paper. Hopefully it can<strong>in</strong>spire others to use satellite <strong>in</strong>terpretation exercises <strong>in</strong> their class practice.References1. ANON 1997.
