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.
25 Years of Landsat
In honour of the twenty year anniversary in 2004, our Landsat Showcase was created to present some of these images and show how some of the world's cities have changed and developed through the duration of the mission.
