Minimize About Earth Watching

The Earth Watching project started at the end of 1993 during an emergency in Germany caused by serious floods that lasted for several days in the Cologne - Bonn area.

We realised that during natural disasters, users and governmental authorities need data over the affected areas in very short timeframes, shorter than normal data delivery times, in order to co-ordinate rescue activities.

The Earth Watching project aim is not only to show natural disasters, but also to promote various satellite remote sensing applications through images and articles. Some examples are shown in the change detection part of this website.
