Change Detection

Within scientific objectives the change detection is an important tool. For over 30 years satellite images provide the potential to realise a worldwide and temporal monitoring.

Example: change monitoring of lakes using satellite images from 1988 to 2008

Fig. 1: The analysis of the expansion of the lake surface shows a clear siltation process within the last 20 years (backround image: false colour image of 1988)

Fig. 2: The change detection of the suspended matter shows an increase from 1988 to 2008

Fig. 3: Chlorophyll content increased over the last 20 years
