Forest fires claimed a large number of lives and caused great ecologic damage in the Mediterranean in the past years. During the summer and while the fires last, the media coverage is extensive – one can watch countless reports on the course of the fires, listen to interviews on losses and human tragedies, and read about backgrounds. But what about the developments in the affected regions after such a disaster? In order to derive statements on the development of ecosystems out of balance, the use of remote sensing data is advantageous, since it allows the comparison of different points in time, thereby, showing the development and change. Most Geography curricula include natural disasters and/or interactions between nature and human interferences (e.g. with spatial effects or effects on geo-ecological cycles). This teaching unit combines both topics and analyses how a “natural” disaster, triggered or expedited by humans and, therefore, being a human interference with nature, effects the development of landscapes. The utilisation of satellite images in this case is particularly beneficial for they facilitate the analysis of an area at different points in time. Thereby, one may for example derivate conclusions on the development of landscapes in interaction with disastrous processes caused by humans. Especially the display of so-called vegetation indices allows conclusions on the vitality of plant stocks. The goal of the teaching unit "traces of fire in satellite images" is to point out the coherences between the electromagnetic spectrum, the production of satellite images and the detection of alterations within ecosystems. The teaching unit utilises the facilities of the computer for effectively conveying the issue by using animations and interactive applications. The topic complex is practically approached via a computer-based interactive learning module. The analysis tools within the learning module – NDVI or time series analysis – are programed in a new, clear and pupil-oriented fashion in Flash AS 3.0.
