Environmental pollution is a serious global problem that has become a major threat to the survival of the world we live in. Now it is possible to prevent natural and man-made disasters caused by pollution by using the ERS data.
The ERS data is applicable for solving ecological problems:
- detection of pollution sources
- appraisal of the state of the environment;
- estimation of gas emissions quantity;
- disasters prediction and warning (landslides, flooding, waterlogging).
Advantages:
Depending on different purposes specialists use different types of the ERS data. For example, medium resolution data is used for the identification of pollution sources of lands and waters; infrared imagery is used to identify oil spills while visible imagery is required for fugitive dust monitoring. Remote sensing makes a constant monitoring of rapidly changing ecosystems possible.
