Earth Observing Systems(EOS) consists of numerous satellites in orbit around the planet. These satellites allow us to view any part of the planet at any time. It was designed so that air, land and oceans can be observed and measured without travelling to the locations.
History:
Many satellites were first launched as part of a military operation to allow better understanding of the terrain they were fighting in. being able to view the terrain allowed the military to plan routes for transport and troop advancement. It also allowed them to see targets without sending planes or troops.
NASA then began sending satellites into orbit and the information obtained was made visible to the public. These satellites allow the government to monitor the levels of pollution in the atmosphere as well as providing visual images of the earth. Between August 1997 and October 2006 nearly 20 satellites were launched as part of the EOS program with a further 4 set to be launched in the near future.
Remote Sensing for World Heritage Conservation
Remote sensing is great for supporting world heritage conservation, they can help the process of conservation in natural park, landscapes and cultural sites.
We can create very recent maps, monitor vegetation and land change.
Areas that may not be accessible by land for example the Amazonian rainforest, can be mapped using remote sensing and then we can produce digital terrain model’s (DTM).
GEOSS in Remote Sensing
Satellites in orbit around the Earth can help monitor natural disasters such as;
- Forest Fires
- Earthquakes
- Land Slides
- etc.
The areas which are vulnerable to these disasters can be monitored and should they occur the spread can be predicted. Using this GEOSS system means that plans to avoid, to counter and to contain these disasters can be drawn up.
