Monitoring of water pollutants
Aerial Remote sensing can monitor pollutant substances and detect water pollution problems in water areas through aerial Remote sensing; First to know about the Remote sensing, Remote sensing is to point to in the case of no direct contact with the target object, distance of target object detection, recognition and feature information, the process of electromagnetic waves, sound waves in space, gravity field can be used as a Remote sensing, but usually described in the Remote sensing refers to the use of electromagnetic waves for target feature information of Remote sensing of electromagnetic waves. Since any object with a temperature higher than absolute zero can emit, reflect or absorb energy radiation, and different objects have different properties and structures, different ground objects have their unique radiation characteristics. Similarly, in water environment monitoring, water bodies with different temperature, sediment content, algae quantity and pollution degree also have different radiation characteristics. Usually, the characteristics of various water bodies can be reflected by Remote sensing images. Polluted water has spectral characteristics different from clean water, which are reflected in the absorption or reflection of specific wavelength, and these spectral characteristics can be captured by Remote sensing devices and reflected in Remote sensing images. Based on the recognition of images, we can obtain water quality parameters or water pollution status. Based on this, Remote sensing technology can be applied in water environment monitoring.
